DESCRIPTION

Description

The differential temperature controller smart Stove is an independent electronic controller for controlling heating and water temperatures for use with hydrophilic wood log and pellet stoves in combination with one or more buffer tanks.

The controller is equipped with a robust three-part plastic housing which can only be opened by means of tools (screw driver PH2).

Operation is effected by means of only two control elements; indications appear against a backlit colour display.

Scope of supplies

• Differential temperature controller smart Stove

• Operating Instructions

Mounting and connection

Before connection of the electrical system, the controller must be mounted firmly to a perpendicular, robust surface (wall), see

For its own supply and the supply of the outputs, the controller must be connected to an electrical energy supply system in accordance with the technical data, see

“Mounting” on page 40.

“Electrical connection” on page 44.

DANGER

Loose installation or connection

Lethal danger due to electrocution!

Whenever work is performed on the open terminal cover, all poles of the power supply must be disconnected reliably and protected against being switched on again!

Assembly, connection, commissioning, repair and disassembly of the controller are only admissible in a specialist workshop.

NOTICE

Each temperature sensor has two connectors which are equivalent, i. e. interchangeable. Thus, polarity reversal is not an issue.

The sensor lines can be extended up to a length of 100 m, to this effect, a cable cross section of

x 1.5 mm2 is recommended.

To ensure correct operation, temperature sensors type Pt 1000 must be used - the sensor design does not affect function.

FUNCTIONS FOR STOVE CONTROL

Functions for stove control

Fire detection

The “fire detection” recognizes, if fire in the wood log or pellet stove is burning.

When fire is detected, a flame symbol will be displayed ( or ).

Fire detection is performed by monitoring the stove temperature (TS1).

Fire detection with pellet stove

If a system with a pellet stove is configured, the option “fire detection with pellets” is available to allow fire detection in combination with pellets.

• If “fire detection with pellets” is enabled, fire will be detected on and off in the same manner as with wood log stove.

• If “fire detection with pellets” is disabled, the flame symbol will be highlighted when the request for heat from the stove (RO1) is active.

Dynamic pump delay (DPD

When the stove is fired, a start condition for the charging pump must be fulfilled.

The dynamic pump delay ›DPD‹ is calculated as the product of temperature and time from the point when the stove temperature (TS1) passes a set stove temperature ›Charge start‹. When the set value of ›DPD‹ is reached, the pump starts.

The dynamic pump delay can be set in professional mode, see “Basic functions” on page 55.

Dynamic pump control

The charging pump should be speed-controlled to maintain a fixed stove temperature.

During commissioning, see “Checklist” on page 51, between dynamic pump control, pump speed control, or combination of both must be selected. Speed control is available only for high efficiency pumps (PWM or analog 0-10 V).

• In case of using a fixed-speed-pump, the start of the pump is triggered by reaching a fixed stove temperature ›Charge start‹ and the fulfilled dynamic pump delay ›DPD‹. The dynamic pump con trol is activated when the stove temperature (TS1) rises above the set stove temperature ›Charge start‹.

• In case of using a speed-controllable pump, the start of the pump (at minimum speed) is triggered by reaching a fixed stove temperature ›Charge start‹ and the fulfilled dynamic pump delay ›DPD‹. The control of the pump is triggered by fulfilling a separate set-point (›Charge start‹ + ›Charge off set‹) and the product of an increment factor with the minimum pump speed.

The following diagram illustrates the dynamic pump delay and dynamic pump control.

FUNCTIONS FOR STOVE CONTROL

The pump starts when a fixed stove temperature ›Charge start‹ and the dynamic pump delay ›DPD‹ are reached (›Charge start‹

The pump increases its speed above (›Charge start‹ + ›Charge offset‹). With each temperature increase by 1 K it will speed-up by an adjustable increment (default 5%).

The parameters for dynamic pump control can be set in professional mode, see “Basic functions” on page 55.

Overtemperature protection

The temperatures of the stove and the tanks are monitored. When overtemperature occurs, at wood-log stove the charging pump is forced to run. At pellet stove the stove is forced to stop.

The temperature limits can be changed in professional mode, see “Basic functions” on page 55.

* dt).

NOTICE

In order to avoid overheating, the wood log or pellet stove must be equipped with its own overtemperature protection.

smart Stove - 0142 - 42WMSUGAT2-C 25

FUNCTIONS FOR STOVE CONTROL

Antifreeze protection

If the temperature at any sensor falls below the set value (AF, factory setting: 3°C, range: 2°C 10°C), the pumps will be are activated at 100%. In addition, an alarm message will be generated (buzzer alarm selectable).

The parameters for antifreeze protection can be set in professional mode, see “Protective functions” on page 63.

Anti-legionella function

To avoid possible affection of legionella at domestic hot water, a cyclic, thermic treatment shall take place.

The anti-legionella function is only available, if domestic hot water heating is designated by the selected hydraulic system.

The anti-legionella functions checks if the minimum temperatures for reduction of legionella has been achieved in the tank due to heating activity within a set interval.

If no sufficient heating has taken place, the water will be heated up to disinfection temperature, specifically for reduction of legionella.

The installer must set the parameters based on the applicable general directives and local requirements. The time of the disinfection cycle can be determined freely.

The parameters for anti-legionella protection can be set in professional mode, see “Basic functions” on page 55.

Additional heating

A dynamic recharge delay (DRD) postpones the activation of the additional heating. Before the additional heating is activated, the dynamic recharge delay has to expire.

The dynamic recharge delay is calculated by the minutes*degrees product. The recharging will start at the calculated temperature point.

The DRD value can be set between 0 and 500 min*K (minutes * degrees Kelvin).

• With DRD = 0, the delay is disabled, additional heating will start immediately.

• Example DRD = 50 min*K: If the tank temperature falls by 10 K (e.g. from 50°C to 40°C), additional heating will start after 5 minutes (5 min * 10 K = 50 min * K). If the tank temperature falls by 5

K, additional heating will start after 10 minutes (10 min * 5 K = 50 min * K).

• Example DRD = 100 min*K: If the tank temperature falls by 10 K, additional heating will start after 10 minutes (10

With a bar graph inside of the heat-generator symbol, you will be informed about the progress of the dynamic recharge delay.

During the falling of the tank temperature the following will happen:

• When the tank temperature falls below the set-point for additional heating, the calculation will be started and the bar graph will start with a fully green coloured circle inside of the tank symbol.

• When the tank temperature reaches the calculated temperature of the dynamic recharge delay, the symbol inside of the tank will switch to fire or electrical flash and the recharging is started.

The parameters for additional heating can be set in professional mode, see “Basic functions” on page 55.

FUNCTIONS FOR STOVE CONTROL

Request for heat

The controller system is designed to control heat for space heating and domestic hot water separately.

For each demand a separate setpoint can be adjusted, one for request heat by stove, one to request heat by an additional heater.

For example:

• Domestic hot water (DHW) setpoint stove = 65°C

• Domestic hot water (DHW) setpoint additional heater = 55°C

• Space heating (SH) setpoint stove = 50°C

• Space heating (SH) setpoint additional heater = 40°C

An occurring demand by temperature conditions is visualized by little symbol on the information screen:

Request for heating domestic hot water

Request for space heating

Request for heat with wood log stove

With a wood log stove, a demand will activate an orange blinking background on the stove symbol as an invitation to make fire. With an little delay, a buzzer will assist the request. The buzzer can be enabled/disabled optionally.

If fire is made in the stove, it will be detected and the charging pump will be activated and controlled automatically. With reaching the setpoint (stove), the related demand symbol will vanish.

With undercutting the setpoint for additional heater, what should be set always clear below the setpoint for stove, the additional heater will be activated immediately related to selected mode (comfort) respectively with dynamic delay (eco).

Request for heat with pellet stove

In combination with an pellet stove, an occurring demand from domestic hot water or space heating by the stove setpoint will activate the pellet stove. If it is enabled for providing heat, fire will be detected and displayed, similar to wood log stove.

Request for additional heater is working in the same way as in wood log schemes.

Temperature thermostat “Window”

The window function is similar to a thermostat function, but with an additional threshold to start and stop the output. The “window” is defined by two temperature values (lower and upper limits), each within a defined range. A fixed hysteresis of ±1K for start and stop is added onto the defined limits.

Only a free (unused) output can be used for the window function. The relay can also be driven inverted.

The output is activated, if the temperature is between upper and lower limits (± hysteresis).

• The output is switched ON when the lower limit + hysteresis or the upper limit - hysteresis is reached.

• The output is switched OFF when the upper limit - hysteresis or the lower limit + hysteresis is reached.

Ter minals

The differential temperature controller smart Stove is connected by four three groups of spring-type terminals which are visible once the terminal cover is opened.

To introduce the cables, release the three screws on the strain relief device; if necessary, remove the strain relief device.

In case of flush mounting of the cables, the break-out segments in the housing base can be removed carefully and the cables routed through these ports.

The central terminal block is the interface to a potential-free change-over contact - here, it may be necessary to route electrical resistors into the spring-type terminals and to connect part of the cables via luster terminals.

44 smart Stove - 0142 - 42WMSUGAT2-C

ELECTRICAL CONNECTION

The strain relief device can only ensure solid clamping if the cables are not stripped to a length of over 35 mm.

Insulation of the individual wires must be removed over a length of 9 10 mm to ensure safe electric contact in the spring-type terminal.

Stranded wires must be provided with cable end sleeves!

For connection, press the actuation push button of the spring-type terminal using a screwdriver and insert the wire to its stop in the appropriate port.

Release the actuation push button and pull the cable slightly to ensure that it is safely clamped.

The spring-type terminals for the power supply, RO1, RO2 and REL, and for TS1 to TS8 can accom-

modate solid wires up to a cross section of 1.5 mm2. Appropriate stranded wires must be preassembled with cable end sleeves.

For the strain relief device function, TS1 to TS7 and REL require cable diameters of at least 5 mm, for Power, RO1, RO2 at least 7

The strain relief fixture can be slightly reworked to fit larger cable diameters without producing sharp edges. For a larger number of sensor lines, cable straps can be used to support the strain relief.

Activate ›Mirror system‹ if your plant is that way.

Note: ›Mirror system‹ does not influence the functions of the controller.

The further menu items depend on the selected hydraulic system.

If a temperature sensor for space heating is installed, select it by the ›Supply Sensor‹ item.

If an outdoor temperature sensor is installed, select it by the ›Outdoor Sensor‹ item.

Note: The availability of temperature sensors depends on the selected system. By selecting a temperature sensor, the regarding functions are enabled simultaneously.

NOTICE

In professional mode, settings are made which require detailed knowledge of the heating as well as wood log or pellet stove plants.

Moreover, solid specialist knowledge regarding control engineering, hydraulics and wood heating is required!

If a single parameter is changed, this may affect the safety, function, and efficiency of the entire plant!

Leave the settings in professional mode to a specialist workshop, the installer!

Modifications by non-experts tend to result in damage to the plant, rather than to an improvement of its efficiency!

To enter the professional mode, select ›1.7 Login‹ from the main menu, activate it and ...

... enter the access code.

The access code to professional mode is ›365‹.

The fact that the installer must be available for his/her customers on 365 days per year may serve as a mnemonic trick.

If the professional mode is not exited actively, the controller automatically displays the plant layout after the preset display shut-off time and the access code is reset to 350.

MALFUNCTION

NOTICE

If a malfunction message appears in the display, the operator can define the possible causes by means of the ›Service Wizard‹ so that he/she can provide the installer with precise information.

There may be various deficiencies in a thermal system, which require a wide variety of approaches. The controller communi cates every step to the operator or installer via the screen, so that there is no need to describe all malfunctions in detail in this operating manual.

DANGER

Repair or disassembly

Lethal danger due to electrocution!

For troubleshooting on the plant, disconnect all poles of the power supply reliably and protect it them against being switched on again!

Sensor monitoring

The temperature sensors TS1 to TS6 are monitored for short-circuit or interruption. A sensor fault (interruption or short-circuit) is indicated in the model diagram by three minus signs:

The controller has stored temperature limits which comprise the temperature range that is usually to be expected for a heating control. If this range is left, the controller signals an error.

In case of use of PT1000 sensors, the following limits have been established:

• Short-circuit: Measured temperature ‹ -30°C (resistance ‹882 )

• Interruption: Measured temperature › 250 °C (resistance ›1.931 )
