IV. How to use the controller
IV.1. Principle of operation
The regulator controls the fan and the fuel feeder operation so that the pre-set temperature of the CH boiler and the water tank is reached. Additionally, it controls CH and DHW pump operation activating them once a pre-defined temperature of the CH boiler has been reached.
IV.2. Stages of operation
Fire-up – this phase is initiated when the flue gas temperature reaches a pre-set value and does not drop below this value for 30seconds (default fire-up time). Operation – when the fire-up phase has been completed, the controller enters operation mode and the display shows the message ‘PID: OPERATION’. It is the primary mode of controller functioning when the blow force and fuel feeding are regulated with PID algorithm, oscillating around the pre-set temperature defined by the user. When the temperature increases unexpectedly by more than 5oC above the pre-set value, the supervision mode is activated. Supervision mode – this mode is activated automatically when the temperature exceeds the pre-set value by more than 5oC in operation mode. In such a case, the controller disables PID control and uses manual settings (according to parameters defined in the fitter's menu).The display shows the following message: ‘PID: SUPERVISION’
IV.3. zPID control
ST-550zPID is a controller with continuous output signal, using zPID algorithm. This type of controller calculates the blow force on the basis of CH boiler temperature and the flue gas temperature measured at the CH boiler outlet. The fan operates continuously and the blow force depends on the CH boiler temperature, the flue gas temperature as well as the difference between these parameters and their pre­set values. One of the greatest advantages of zPID regulators is their ability to maintain a stable pre-set temperature without unnecessary overregulation and oscillations.
Apart from zPID control, the controller operation is adjusted on the basis of the the readings from
the air flow sensor mounted on the fan.
Using this type of regulator with a flue gas sensor helps to reduce fuel costs by up to several percent. Moreover, it ensures stable temperature of output water thus prolonging the life of the heat exchanger (of the CH boiler). Flue gas temperature control results in low emission of dust and environmentally harmful gases. Flue gas heat is not disposed of through the chimney, but it is utilised for heating purposes.

TEST RESULTS - TECH controller without PID control:
IV.4. Controller operation without zPID control
zPID control may be disabled at any time using Operation algorithm selection parameter. Additional submenu will appear in the controller menu, allowing the user to configure boiler operation parameters. Once zPID control is disabled, the principle of operation is changed - after the fire-up stage the controller enters operation mode which is followed by sustain mode: Operation – once the controller is switched on, it enters operation mode and OPERATION appears on the display. It is the primary mode of controller operation in which the fan operates continuously and the fuel feeder operation is adjusted according to user’s settings. The user defines both the operation time and pause time.
Sustain mode – this mode is activated automatically if the temperature is equal or higher than the pre­set temperature value. Fuel feeding process slows down in order to smoothly reduce the temperature of the circulating water. SUSTAIN appears on the display. In order for the temperature to decrease properly, it is necessary to configure operation and pause time in sustain mode as well as the fan speed.

V.2. Fire-up
This function enables the user to easily fire-up the CH boiler. After initiating the fire manually (preparing the furnace and starting the fire), the user activates automatic fire-up phase in the controller menu. The controller conducts the fire-up process maintaining the blow and gradually feeding fuel. Thanks to optimum parameters, CH boiler smoothly switches to operation mode.
Once the CH boiler entered operation mode, instead of Fire-up function the menu displays Damping function, which may be used to activate damping process.
V.3. Screen view
This function is used to choose between standard screen view and test screen view (secured with a code).
V.4. Fuel tank full
This function should be used after the fuel tank has been fully filled, in order to reset the fuel consumption percentage to 100% (the value displayed in the top right-hand corner of the main screen, below the clock).
NOTE: Before using this function for the first time it is necessary to calibrate the fuel feeder operation in the fitter’s menu.
V.5. Temperature settings
V.5.a) Pre-set CH temperature
This option is used to define the pre-set CH boiler temperature. The setting rage is 45⁰C do 80⁰C. The pre-set temperature may also be changed with the use of weekly control function. The pre- set temperature is the sum of all these values but within the range of 45⁰C do 80⁰C.
V.5.b) CH hysteresis
This option is used to set the hysteresis of the pre-set temperature. It is the difference between the temperature of entering the sustain mode and the temperature of restoring operation mode (for example: when the pre-set temperature is 60 ºC, the hysteresis is 3ºC, entering sustain mode takes place at the temperature of 60 ºC whereas returning to the operation mode takes place at 57 ºC).
V.5.c) Pre-set DHW temperature
This function is used to define the pre-set temperature of the domestic water (this function is inactive when house heating mode is selected). This value may be adjusted directly from the main screen view. After the tank water reaches this temperature, DHW pump is disabled. The pump will be enabled again when the temperature drops below the pre-set temperature by a pre-defined value.
V.5.d) DHW hysteresis
This option is used to set the hysteresis of the pre-set water tank temperature. It is the difference between the pre-set temperature (desired temp. of the water tank when DHW pump is switched off) and the temperature at which DHW pump is activated again (for example: when the pre-set temperature is 55 ºC, the hysteresis is 5ºC, DHW pump is switched off and CH pump is enabled when the pre-set temperature of 55 ºC is reached. DHW pump is activated again when the temperature drops to 50 ºC).
V.5.e) Temperature of pump activation
This option is used to define the temperature of CH pump and DHW pump activation (temperature measured on the CH boiler). Below this temperature value both pumps remain inactive whereas above this value the pumps are enabled and operate according to the operation mode (see: pump operation modes).

V.5.f) Pre-set room temperature
Once a room regulator with RS communication has been connected and activated in the controller menu (Fitter’s menu/Room regulator), the user may adjust the pre-set room temperature.
V.6. Manual mode
For the user's convenience, the regulator offers manual mode function. In this function, each executive device may be activated and deactivated independently of others. It is an easy way of checking if the following devices work properly: feeder, blow (fan), CH pump, DHW pump, additional pump 1, additional pump 2, built-in valve1, built-in valve 2, valve 1, valve 2). Additionally, the user may adjust the fan speed in manual operation mode using blow force function.
V.7. Operation settings
NOTE: This submenu is available only when PID control is disabled - see: Controller operation without zPID control.
V.7.a) Feeding time
This option is used to set the operation time of the fuel feeder. It should be adjusted to the type of fuel and CH boiler used.
V.7.b) Pause time
This option is used to set the pause time of the feeder. The length of the pause should be adjusted to the type of fuel used. Incorrect pause time may result in inefficient operation of the CH boiler, i.e. unburnt coal left or failure to reach the pre-set temperature of the CH boiler. Appropriate pause time ensures efficient operation of the CH boiler.
V.7.c) Blow force
This function is used to control the fan speed. The setting range is 1-100% (it may be regarded as fan gears). The higher the gear is, the faster the fan works. 10% is the minimum fan speed whereas 100% is the maximum fan speed. Initially the fan always operates at a full speed, which enables successful activation even if the motor is dusty.
V.7.d) Operation in sustain mode
This option is used to set the operation time of the feeder and the fan when the CH boiler operates in sustain mode.
V.7.e) Pause in sustain mode
This option is used to set the fuel feeding pause time when the CH boiler operates in sustain mode. Incorrect setting of pause and operation time may result in farther temperature increase, unintended CH boiler damping or lead to fuel ignition hazard in the fuel tank.
V.7.f) Fan in sustain mode
This option is used to set the fan operation and pause time in sustain mode.
V.7.g) Fan speed in sustain mode
This option is used to set appropriate fan gear (blow force) in sustain mode.
V.8. Fuel granulation
This function is used to choose one of the two levels of fuel granulation: coarse or fine. For each level there is suitable blow force and fuel feeding frequency programmed.

V.9. Operation modes
V.9.a) House heating
When this function is selected, only the house is heated. CH pump is activated when the temperature is above the pump activation threshold (factory setting). Below this temperature value (minus 2OC – hysteresis) the pump is disabled.
V.9.b) Water tank priority
In this mode, the DHW pump is activated first and it operates until the pre-set DHW temperature is reached. After the pre-set temperature has been reached, the pump is switched off and the CH pump is activated.
CH pump operates continuously until the water tank temperature drops below the pre-set value minus DHW hysteresis. Then, the CH pump is disabled and the DHW pump is activated.
In this mode, the fan and the feeder operation is limited to 72 OC at the CH boiler in order to prevent the CH boiler from overheating.
WARNING:
Return valves should be installed on the circuits of the CH and DHW pumps. The valve on DHW pump prevents hot water from being sucked out of the water tank.
V.9.c) Parallel pumps
In this mode, both pumps are activated simultaneously above the pre-set activation temperature (default setting: 40 ºC). CH pump operates all the time whereas DHW pump is disabled when the pre-set water tank temperature is reached.
V.9.d) Summer mode
In this mode, CH pump is switched off and DHW pump is enabled above the pump activation threshold (default setting: 40OC) and operates all the time above this threshold. In summer mode the user defines only the pre-set temperature of the CH boiler which heats the domestic hot water (this value also serves as the pre-set water tank temperature). After this function has been activated, the screen displays current CH temperature and two DHW temperature values (the current temperature value and the pre-set one).
V.10. Weekly control
Weekly control function enables the user to program changes of the pre-set CH boiler temperature (CH weekly control) or water tank temperature (DHW weekly control) for particular hours and days of the week.
In order to activate this function, select mode 1 or mode 2. Detailed settings of each mode are available further in the submenu: Set mode 1 and Set mode 2. Once a given mode is selected, the main screen displays the value of current temperature deviation (below the pre-set CH temperature, alternately with Pre-set) informing the user that the function is active.
How to change weekly control settings:
ST-491 controller enables the user to program weekly control function in two modes: MODE 1 – the user sets the temperature deviations for each day of the week separately; MODE 2 – the user sets the temperature deviations for all working days (Monday-Friday) and for the weekend (Saturday-Sunday) separately.
How to configure mode 1:
In order to configure mode 1, select Set mode 1 – the display shows the panel with particular days of the week. Once a given day of the week is selected, the screen shows the editing panel – the upper line shows current deviation, the lower line shows the time period. Twist the pulser knob to change the time period. In order to edit the deviation value, press the pulser knob and select Change. In order to copy the setting for the next time period, press the pulser knob and select Copy.

set: 5
00
PM, temp 50C (weekly control setting +50C)
set: 6
00
PM, temp 50C (weekly control setting +50C)
In this case, if the pre-set temperature of the CH boiler is 60
0
C, on each weekday (Monday – Friday) from 300AM to 600AM the pre-set temperature will drop by 100C, so it will be 500C. During the weekend, from 4
00
PM to 7
00
PM the pre-set temperature of the CH boiler will increase by 50C, so it will
be 650C.

V.14.a) Software update
• Software update should be conducted when the CH boiler is damped.
• The memory stick which is going to be used to save the set-up file should be empty (prefer-
ably formatted)
• Make sure that the file saved on the memory stick has exactly the same name as the down-
loaded file so that it is not overwritten.
Insert the memory stick with the software into the controller USB port. Reset the device by unplugging it and plugging it back in. When the controller starts again, wait until the software update process starts.
o Once restarted, the controller display shows the starting screen. o Software update starts automatically. o During installation process colourful stripes appear on the screen illustrating the installation
progress.
o Once the installation process is completed, the display shows the main screen.
Once the software update has been completed, you can remove the memory stick from the USB
port.
The software update of ST-66P module may be conducted in a similar way by inserting the memory stick with the software into the USB port of the additional module.
V.15. Factory settings
The controller is pre-configured for operation. However, the settings should be customized to the user's needs. Return to factory settings is possible at any time. When the factory settings option is activated, all customized settings of the CH boiler (saved in the user's menu) are lost and replaced with the manufacturer's settings. Then, the parameters may be customized anew.
VI. Controller functions - Fitter’s menu

VI.1. PID coefficient
NOTE This submenu concerns CH boiler operation with PID control and t is available only when zPID control is active.
VI.1.a) CH boiler power coefficient
CH boiler power coefficient serves to control the feeder and fan operation at the same time. 100% is the default value but it may be adjusted within the range of 50-110%. Once a change is introduced, the upper limit of zPID parameters is moved (operation/pause time of the feeder and blow force). The lower limit of parameters remains unchanged.
VI.1.b) Fan correction bottom / Fan correction top
This function is used to adjust the fan speed. If the blow force is too low/high, the coefficient should be adequately increased/decreased in order to ensure efficiency. The user may adjust the fan speed for both minimum and maximum CH boiler power indicated by zPID (Fan correction bottom and Fan correction bottom parameters).
VI.2. PID supervision
NOTE
This submenu concerns CH boiler operation with PID control and t is available only when zPID control is active.
In this function the user configures the combustion parameters for the situation when the CH boiler temperature exceeds the pre-set value by 5°C. If Damping mode function is selected, the damping process is initiated when the pre-set temperature value is exceeded by 5°C. Once the process is completed, the controller constantly monitors the CH boiler temperature. If it drops by a pre-defined vale, the fire-up process is initiated again.
NOTE
Damping mode concerns only pellet-fired CH boilers controlled with the use of an additional ST-66P module.
The remaining options should be configured if the user does not want the CH boiler to be damped when the controller enters supervision mode. The user sets fuel feeding time, feeding pause as well as fan operation and pause time during fuel feeding (blow-by gear)
The function is deactivated automatically when the CH temperature drops to the pre-set value.
VI.3. Buffer parameters
NOTE
Function available only when ST-66B module is used.
These parameters enable the user to configure controller operation settings in the case of heating systems with a buffer.
VI.3.a) Buffer
Once buffer function is activated (by selecting ON) , CH pump serves as pump of the buffer in which two sensors are installed: upper (C1) and lower (C2). The pump remains active until the pre-set temperature of buffer bottom is reached. When the temperature drops below the pre-set buffer top temperature, the pump is activated again.
VI.3.b) DHW function
If buffer is used in the heating system, it is necessary to specify how the water tank is connected:
- from CH boiler – the heating system in which DHW tank is connected directly to the CH boiler (a separate circuit).
- from buffer – the heating system in which DHW tank is built in or connected to the buffer.
ST-550 zPID
19
VI.3.c) Pre-set temperature top
This function enables the user to define the pre-set temperature for the upper part of the buffer (sensor should be placed in the upper part of the tank). After this value is reached, the pump is disabled (provided that the pre-set buffer temperature bottom has also been reached).
VI.3.d) Pre-set temperature bottom
This function enables the user to define the pre-set temperature for the lower part of the buffer (sensor should be placed in the lower part of the tank).
VI.4. Valve settings
VI.4.a) Built-in valve, Additional valve 1 and 2
These options are used to configure operation of the built-in valve. The built-in module controls two valves without the need to use additional devices. It the heating system requires other devices, an additional module controlling the valve (e.g. ST-431N) may be connected to the ST-550zPID controller. The parameters included in the submenus Valve 1 and Valve 2 are intended for controlling such valves. In the case of valves 1 and 2, it is necessary to register in order for the valve to operate correctly. To register the valve, enter the module number (placed on the casing) and configure a few parameters. There is a range of parameters intended for configuring the operation of the valves and adjusting it to the user’s needs. Both the parameters of the built-in valve and the parameters of the valves are similar, which is illustrated by the following block diagrams:

Temperature control
This parameter determines the frequency of water temperature measurement (control) behind the CH or DHW valve. If the sensor indicates a change in temperature (deviation from the set value), then the electric valve will open or close by the set stroke, in order to return to the pre-set temperature.
Opening time
This parameter defines the time needed for the valve actuator to open the valve from 0% to 100% position. This value should be adjusted to the value given on the actuator rating plate.
Single stroke
This function is used to define the maximum single stroke (opening or closing) that the valve may make during one temperature sampling.
Minimum opening
This function is used to set the minimum value of valve opening. The valve does not close any further.
Valve type
This option is used to select the type of valve used.
For the function of weather control to be active, the external sensor mustn't be exposed to sunlight or influenced by the weather conditions. After it is installed in an appropriate place, weather-based control function needs to be activated in the controller menu.
For the valve to operate correctly, the user defines the pre-set temperature (behind the valve)
for 4 intermediate external temperatures:
TEMP FOR -20ºC TEMP FOR -10ºC TEMP FOR 0ºC TEMP FOR 10ºC
Heating curve – it is a curve according to which the pre-set controller temperature is determined, on the basis of external temperature. In our controller, this curve is constructed on the basis of four pre-set temperatures for respective values of external temperatures. The more points constructing the curve, the greater its accuracy, which allows its flexible shaping. In our opinion, four points seem a very good compromise ensuring decent accuracy and easiness of setting the course of this curve.
In our controller: XA = -20ºC, XC = 0ºC, XB = -10ºC, XD = 10ºC, YA, YB, YC, YD – pre-set temperatures of the valve for respective external temperatures: XA, XB, XC, X
D
After weather-based control function has been activated, pre-set valve temperature function is no longer available.
Return protection
This function enables the user to set CH boiler protection against too cool water returning from the main circulation, which could cause low-temperature CH boiler corrosion. The return protection involves closing the valve when the temperature is too low, until the short circulation of the boiler reaches the appropriate temperature. This function also protects the CH boiler against too high temperature by preventing the returning water from boiling. After activating it, the user pre-sets the minimum and the maximum acceptable return.
User’s manual
22
Sensor selection
Option available only for valve 1 and valve 2. When two mixing valves are used, this option enables the user to specify which sensors should be used to provide temperature data for the valve (for external temperature sensor and return sensor). The temperature values may be read from the sensors of the selected valve (Own) or valve 2 sensors (module2).
Room regulator
This option is used to define how the room regulator settings will influence particular valve status.
Room regulator – the user should select the type of a room regulator cooperating with the valve. The following options are available:
OFF – room regulator status does not influence valve settings; TECH regulator– a regulator with RS communication; Proportional regulation – option available only with TECH regulators offering RS communication
function. It is necessary to configure two options: change of pre-set valve temp. and room temper­ature difference.
Room reg. temp. lower - When the room regulator reaches the pre-set temperature, the pre-set valve temperature drops by the value defined in this parameter.(Option unavailable when Proportional regulation is selected.)
Change of pre-set valve temperature – This setting determines by how many degrees the valve temperature is to increase or decrease with a single unit change in room temperature (see: Room temperature difference). This function is active only with TECH room regulator and it is closely related to the Room temperature difference parameter.
Room temperature difference - This setting is used to define the single unit change in the current room temperature (with the accuracy of 0.1°C) at which a predefined change in the set temperature of the valve will be introduced (function available only with TECH room regulator).
Maximum floor temperature
This function is used to define the maximum temperature of the valve sensor which does not damage the underfloor heating system. It is used when floor valve is selected as the valve type. Once this temperature is reached, an alarm is activated and the valve is closed completely. When maximum floor temperature is reached, CH boiler protection function is deactivated. In such a case, protection of the underfloor heating system is given a higher priority.
External temperature correction
Option available only for additional valves 1 and 2. This function is used to calibrate the external temperature sensor.
Factory settings
This function enables the user to restore the factory settings for a particular valve. Restoring factory settings does not change the selected valve type (CH or floor).
Valve removal
Function available only for additional valves 1 and 2.
This option is used to remove the valve from the controller memory. Valve removal is used e.g. at disassembling the valve or module replacement (re-registration of a new module is necessary).
ST-550 zPID
23
Valve pump
This option enables the user to select the working mode of the pump out of the following:
➢ always ON - the pump operates all the time, regardless of temperatures, ➢ Never- the pump is permanently deactivated and the regulator controls only the valve opera-
tion,
➢ ON above the threshold - the pump is activated above the pre-set switch on temperature.
In the case of additional vales, these settings concern the pump connected to the valve module (e.g. ST­431N). In the case of a built-in valve, these settings concern the additional pump which has been assigned Valve pump operation algorithm.
VI.5. Additional pump 1 / Additional pump 2
These submenus enable the user to select the type of additional pump connected to the additional pump contact (Operation algorithm selection) and configure its operating parameters.
VI.5.a) Algorithm selection
Once the additional pump has been connected, the user selects its type in Algorithm selection parameter. If valve pump is selected, the pump operates according to the parameters configured in the built-in valve submenu (see: previous section). If the additional pump is to serve as short circuit pump or floor pump, it is necessary to configure its operation in the following submenus.
VI.5.b) Short circuit pump
When short circuit pump is selected, the user can adjust the pump operation to individual needs using the parameters available in CH boiler protection pump submenu. The additional pump which serves as a short circuit pump is activated when the CH boiler temperature reaches the user-defined threshold value – Pump activation temperature (measured at CH sensor). The pump remains active until the temperature drops below the pre-set value by hysteresis value.
If other sensor is to serve as CH sensor, it must be selected in CH sensor parameter.
VI.5.c) Floor pump
If floor pump is selected, the user can adjust the pump operation to individual needs using the parameters available in Floor pump submenu. Once the pump is activated (switched on), the user sets the minimum (threshold) temperature of pump activation (measured by CH sensor) and the maximum (pre-set) temperature of the underfloor heating system (measured by the floor sensor, within the range of 25⁰C – 55⁰C). Below the minimum temperature the pump remains inactive. Above this temperature the pump is enabled and it remains active until the maximum temperature is reached – then it is switched off. The pump is enabled again when the temperature drops by the value defined as Hysteresis below pre-set.
If other sensor is to serve as CH sensor or floor sensor, it must be selected in CH sensor parameter or Floor sensor parameter.
VI.5.d) Circulating pump
Once this option is selected, the additional pump serves as the circulating pump. The pump controls the valve which mixes the hot water between the CH boiler and the DHW receivers. The following parameters need to be configured for the circulating pump to work correctly:
Operation time This parameter defines the time of pump operation during its activity. Pause time This parameter defines the frequency at which the circulating pump is enabled during its activity. Operation schedule
The user may program a daily schedule of pump operation and inactivity, with the accuracy of 30 minutes. The pump is enabled at the frequency defined in Pause time parameter and remains active for the time defined as Operation time. For the user’s convenience, it is possible to copy a given time setting.

VI.8. Internet module
ST-550zPID controller has a built-in Internet module which enables the user remote control of the CH boiler via the Internet. The controller must be connected to the Internet router via the Internet cable.
Internet module is a device enabling the user remote control of the CH boiler via the Internet at
www.emodul.pl. The user controls the status of all CH boiler system devices on the home computer
screen and the operation of each device is presented in the form of animation.
Apart from the possibility to view the temperature of every sensor, the user can change the set temperature values for both the pumps and the mixing valves. It also enables the user to fire-up the CH boiler, activate CH boiler damping procedure or adjust the operating parameters online.
The installation process is intuitive. Connect the module and go to Fitter’s menu of the main controller to activate the Internet module (Menu>>Fitter’s menu>>Internet module>>ON). Once Registration option is selected, the device generates a code which must be entered on the website.
NOTE
The code is valid for 60 minutes. If the user fails to register on the website within this time, a
new code must be generated.
Internet module parameters such as IP address, IP mask, gate address etc may be set manually or by selecting DHCP option.
NOTE It is advisable to use Mozilla Firefox or Google Chrome browsers.
• How to log in to the website
After the code has been generated, go to http://emodul.pl and create a new user account:

• Statistics
Statistics tab enables the user to view the temperature values for different time periods e.g. 24h, a week or a month. It is also possible to view the statistics for the previous months.
VI.9. Fuel level calibration
These parameters are used to calibrate the fuel tank. Conducting fuel level calibration properly enables the user to view the current level of fuel on the controller screen. Such calibration is usually performed only once.
The first step involves filling the fuel tank up and selecting the option Fuel tank full (by pressing the pulser knob). The controller remembers the level as full (100%). When there is no fuel left in the tank, the user should select the option Fuel tank empty (by pressing the pulser knob). In this way the fuel tank is properly calibrated.
Each time the tank is fully filled, a corresponding option should be selected in the menu so that the controller will automatically inform the user about the current fuel level.

VI.11. Room regulator
This function enables the user to define the purpose of using the readings from the room regulator:
• CH pump control – the room regulator disables the CH pump when the pre-set temperature is
reached. In this submenu the user specifies which room regulator will control the CH pump: TECH
controller (room regulator with RS communication, connected to RS socket of ST-550zPID
controller) or standard regulator (a two-state room regulator).
• CH boiler control –when the pre-set room temperature has been reached, the pre-set CH boiler
temperature is lowered by the value defined as Room reg. temp. lower parameter (the
temperature does not drop below the minimum pre-set CH temperature). In this submenu the
user specifies which room regulator will control the CH pump: TECH controller (room regulator
with RS communication, connected to RS socket of ST-550zPID controller) or standard regulator
(a two-state room regulator).
EXAMPLE: Pre-set CH boiler temperature: 55ºC Room reg. temp. lower: 15ºC Minimum pre-set CH boiler temperature: 45ºC (factory setting) Once the pre-set room temperature is reached (signalised by the room regulator), the pre-set CH boiler temperature drops to 45ºC, which is 10ºC less although room reg. temp. lower parameter is 15ºC. The main screen displays„!-10º”next to the pre-set CH boiler temperature.
TECH regulator
This function is used to establish communication with the room regulator with RS communication (connected to RS socket in ST-550zPID controller). If this type of regulator is selected in CH pump control or CH boiler control submenu, the communication is activated automatically.
VI.12. External temperature correction
External sensor correction should be performed during installation or after a longer period of using the regulator when the temperature measured by the sensor is different from actual temperature. Range of regulation is -10 to +10 ºC with the accuracy of 1ºC.
VI.13. GSM module
NOTE
This type of control is available only after purchasing and connecting an additional controlling module ST-65 which is not included in the standard controller set.
GSM Module is an optional device which, cooperating with the controller, enables the user remote control of the CH boiler operation via mobile phone. The user is sent an SMS each time an alarm occurs. Moreover, after sending a certain text message, the user receives feedback on the current temperature of all the sensors. Remote change of the pre-set temperatures is also possible after the authorisation code is entered. GSM Module may operate independently of the CH boiler controller. It has two additional inputs with temperature sensors, one contact input to be used in any configuration (detecting closing/opening of contacts) and one controlled output (e.g. a possibility of connecting an additional contractor to control any electric circuit). When any of the temperature sensors reaches the preset maximum or minimum temperature, the module automatically sends an SMS message with such information. A similar procedure is used in the case of opening or closing of the contact input, which may be used as a simple means of property protection. If the GSM Module is to be used with the ST-550zPID controller, it should be activated by selecting ON option (MENU>Fitter's menu>GSM Module>ON).

VII. ST-66P pellet module
ST-550zPID controller may optionally be used to control a pellet boiler via an additional ST-66P module.
NOTE:
Once the module has been installed, Fuel granulation parameter is no longer available in the main menu and Fuel level calibration option is not available in the fitter’s menu.
In the case of pellet boilers, it is possible to remotely initiate both the fire-up and the damping phase via a telephone (an additional GSM module (ST-65) must be connected to the controller).
The principle of operation, certain functions as well as the installation procedure are changed as well.
a) How to install a controller with the module
User’s manual
30
ST-550 zPID
31
b) Principle of operation (controller with pellet module)
The regulator controls fan and fuel feeder operation in the same way as it is done without pellet module. Additionally, if pre-programmed, the controller can start CH boiler damping procedure when the pre-set temperature is reached, and monitor current temperature values. When the temperature drops by a pre­defined value, the controller may start the fire-up process. The regulator may also control the grate operation, which helps to maintain the furnace in proper condition.
c) Stages of controller operation
Parameters of particular operation stages of the CH boiler are configured by the user. Fire-up and damping are multi-stage processes described below. Once the fire-up process is conducted properly, the controller enters Operation mode.
• Fire-up
Fire up process is independent of the selected operation algorithm. This stage is activated by the user in the main menu or by the controller software is certain situations (e.g. when CH boiler temperature decreases - if automatic fire-up/damping function is active). Fire-up process consists of 3 stages:
1. Initial fuel feeding In this stage the blow force is limited to the minimum of 1%. The feeder is enabled and remains active throughout the whole stage.
2. Heater In the next stage, the heater is enabled and operates until the flue gas temperature increases by a pre-defined value. The feeder remains inactive in this stage. This phase lasts until the flue gas temperature increases by 5oC. If the flue gas temperature does not reach the fire-up temperature within a pre-defined time from the heater deactivation, another fire-up attempt follows. After two unsuccessful attempts, the display informs about the fire-up failure. When the fire-up fails, the controller should be switched off at the power switch and the user should check if there is any fuel left in the furnace. If so, the furnace should be emptied. If there is no fuel left, the user should check if there is enough fuel in the fuel tank. Then, the controller should be switched on again and the fire-up process should be activated anew.
3. Delay Delay is the last stage of the fire-up process and it involves stabilizing the controller parameters. Throughout this stage the feeder operates according to operation time and pause time settings and the fan operates at a pre-defined speed.
NOTE:
The furnace needs to be cleared before each fire-up attempt.
• Operation
Once the fire-up process is completed, the controller enters operation mode and the display shows the following message: ‘PID:OPERATION’. It is the primary mode of controller operation in which the fan operation and fuel feeding is automatically controlled with PID algorithm, oscillating around the preset temperature. If the temperature rises unexpectedly by more than 5oC above the pre-set value, the so called supervision mode is activated or the CH boiler is damped.
• Supervision mode
This mode is activated automatically if the temperature exceeds the pre-set value by 5oC when in operation mode. In such a case, the controller disables PID control and uses manual settings (according to parameters defined in the fitter's menu) in order to reduce the temperature of the circulating water ( the display shows the following message: ‘PID:SUPERVISION’), initiates the damping process (if such an option is selected in the fitter’s menu).
User’s manual
32
• Damping
This function is used to damp down the fire and clear the furnace. Damping must be carried out be­fore the disconnected from the power supply.. Such an order must be kept to ensure that all the
fuel is burnt and the remaining ash is removed.
WARNING: Do not switch off the CH boiler at the power strip before carrying out the damping process
Once the damping function is activated, the feeder stops feeding the fuel to the furnace and the fan operates until the flue gas temperature drops below 50oC (default setting).
d) CH boiler operation schedule
Using ST-66P module the user may configure CH boiler operation schedule in the main menu of the controller. It involves selecting days of the week and time of CH boiler operation. Outside these periods the CH boiler remains damped.
e) Grate
It is another option available for pellet-fired CH boilers. . It is used to set the frequency of grate activation, separately for operation mode and sustain mode.
f) Sustain
Function available when ST-66P module is used, only when zPID control is disabled. It enables the user to pre-program CH boiler damping to be conducted every time the CH boiler temperature exceeds the pre-set temperature value by o 5°C. When the temperature drops by a pre-defined value, the fire-up process is initiated again.
g) Fire-up function
If this function is active, the damping process is initiated when the pre-set room temperatures of the controlled devices have been reached. The controlled devices may be e.g. room regulator (if connected and activated), DHW water tank and buffer (if connected and activated). It means that the CH boiler is damped in the following situations:
- in summer mode, when the pre-set DHW temperature has been reached;
- in the remaining operation modes (house heating, water tank priority, parallel pumps), when all
controlled (connected) devices have reached their pre-set temperatures.
After completing the damping process, the controller constantly monitors the temperature of the controlled devices. If any of these values drops to a pre-defined level, the controller starts the fire-up process again.
h) Ash removal (optional)
NOTE:
This function is available only for CH boiler offering automatic ash removal function. It is necessary to activate this function in Service menu.
This function enables the user to set the time and frequency of ash removal procedure.
VIII. Protections
In order to ensure safe and failure-free operation, the regulator has been equipped with a range of safeguards. In case of alarm, a sound signal is activated and the display shows an appropriate message. In order for the controller to return to the operation mode, press pulser knob. In the event of ‘CH
temperature too high’ alarm, it is necessary to wait until the temperature drops below the alarm value.
ST-550 zPID
33
VIII.1. Temperature alarm
This protection is activated only in operation mode (when the CH boiler temperature is lower than the pre-set temperature value). If the CH boiler temperature does not increase within the period of time defined by the user, an alarm is activated: feeder and fan are switched off and a sound signal is activated. The display shows the following message: ‘Temperature not rising'. Press the pulser knob to deactivate the alarm. The controller will resume the previously selected operation mode.
VIII.2. Thermal protection of CH boiler (STB)
ST-550 zPID controller is equipped with STB safety thermostat which protects the CH boiler against an excessive temperature increase. When the temperature reaches 95⁰C (default setting: STB 95oC), the contacts in the fan and feeder power supply circuit are opened. They may be activated again only manually by pressing ‘reset’ button on the safety thermostat casing after the CH boiler water cools down and reaches the temperature of about 80⁰C.
VIII.3. Automatic sensor control
If one of the temperature sensors (CH, DHW, screw feeder or fuel tank) is damaged, an alarm sound is activated and the display message informs about the failure; e.g.: 'CH sensor damaged'. Both the feeder and the fan are disabled. The pump operates regardless of current temperature. If the CH sensor or feeder sensor is damaged, the alarm is active until a new sensor is installed. In the case of DHW sensor damage, the alarm should be switched off by pressing pulser knob – the controller will restore operation with one pump (CH). A new sensor should be installed so that all modes of CH boiler operation could be available.
VIII.4. Protection against boiling of water in the CH boiler
This protection applies only to water boiler priority mode, in the case when the water tank is not sufficiently heated. When the pre-set temperature of water tank is 55OC whereas the actual CH boiler temperature reaches 62OC (so called priority temperature), the controller disables the fan and the feeder. If the CH boiler temperature still increases reaching 80OC, the CH pump will be switched on. In the case of further temperature increase, an alarm will be activated at the temperature of 85OC. Such a situation usually occurs when the water boiler or the pump is damaged or when the sensor is incorrectly mounted. When the temperature drops, at 60OC the controller enables the fan and feeder and it remains in operation mode until the temperature of 62OC is reached.
VIII.5. Temperature protection
The regulator has an additional protection against hazardous temperature growth. If the alarm temperature of 80OC is exceeded, the fan is disabled and the pumps are switched on in order to distribute hot water throughout the house installation. When the temperature of 85OC is exceeded, an alarm is activated and the display shows the following alarm message: ‘Temperature too high’. When the temperature drops to a safe level, press pulser knob to deactivate the alarm. The controller will resume the previous operation mode.
VIII.6. Fuel feeder protection
There is an additional sensor measuring temperature on the screw feeder. In the event of a significant temperature increase (above 80OC), an alarm is activated: the feeder is for 10 minutes, which moves the fuel into the combustion chamber. Feeder sensor prevents the fuel in the tank from igniting.
VIII.7. Limt switch in the fuel tank
In the case of using ST-550zPID controller with such CH boilers as w SOLID, EFEKT, BIO SOLID, BIO EFEKT, the controller monitors the fuel tank flap. Once it is opened, the controller automatically disables the feeder and the fan.
VIII.8. Fuse
The regulator has two WT 6.3A tube fuse-links protecting the network.
NOTE:
Higher amperage fuse should not be used as it may damage the controller

IX. Maintenance
Before and during the heating season, ST-550zPID controller should be checked for condition of its cables. The user should also check if the controller is properly mounted and clean it if dusty or dirty. It is advisable to measure earthing parameters for the motors (CH pump, DHW pump, fan, feeder and circulating pump).
