4 Functions

4.1 Temperature control

General note

Temperature unit selection wizard (only for RDG110U/RDG160TU)

Setting of the control parameters (P01, etc., mentioned throughout the document) is described in section 4.15.

The thermostat acquires the room temperature via built-in sensor, external room temperature sensor (QAA32), or external return air temperature sensor (QAH11.1), and maintains the setpoint by delivering actuator control commands to heating and/or cooling equipment. The following control outputs are available depending on the thermostat type: 1-speed/3-speed fan:

· On/Off control on RDG100, RDG100T, RDG110..

· Modulating PI/P control with 3-position control output on RDG100, RDG100T

· Modulating PI/P control with PWM output on RDG100, RDG100T

· Modulating PI/P control with DC 0…10 V control output on RDG160T..

ECM fan:

· On/Off control on RDG160T..

· Modulating PI/P control with DC 0…10 V control output on RDG160T..

The switching differential or proportional band is 2 K (4 °F) for heating mode and 1 K (2 °F) for cooling mode (adjustable via parameters P30 and P31). The integral action time for modulating PI control is adjustable via parameter P35.

The temperature unit selection wizard enables to select the preferable temperature unit display on thermostats between °C and °F under the following two situations:

1. Select the application via the DIP switches at the rear of thermostat before fitting

the front housing to the mounting plate.

2. Power up the thermostat after successfully connecting the line power.

Display

Concurrent display of °C and °F

Notes

Follow the steps:

1. Rotate rotary knob to select the preferable temperature unit.

2. Press the button (OK) to confirm the selection, and the thermostat goes to

normal operating page.

· Pressing button (Esc) does not confirm the temperature selection.

· If the temperature unit is not selected, °C is used by default.

The display shows the acquired room temperature or the Comfort setpoint, selectable via parameter P06. The factory setting displays the current room temperature. Use parameter P04 to display the room temperature or setpoint in °F rather than °C as needed.

If the thermostat is used in a system with manual heating/cooling changeover (P01 =

2), the heating and cooling symbols on the display show the fan coil or terminal unit's status. Thus, the symbols are displayed even when the thermostat operates in

the neutral zone. For all other cases, the heating and cooling symbols are displayed when the heating or cooling output is activated.

Concurrent display of the current temperature or setpoint in °C and °F (parameter P07) is possible on the thermostats without 7-day time program.

4.2 Operating modes

Select the thermostat's operating mode via the operating mode button on the unit or operating mode input (e.g. keycard occupancy sensor), when X1, X2, or D1 is set to 3 (P38, P40, P42). A corresponding setpoint is used to maintain the room temperature at the desired level depending on the active operating mode. The following operating modes are available:

Comfort mode

Economy mode

Protection mode

Auto Timer mode (with RDG100T,

RDG160T.. only)

Note

AUTO

In Comfort mode, the thermostat maintains the room temperature setpoint which can be adjusted via the rotary knob. The fan can be set to automatic or manual fan speed: low, medium or high.

Economy mode helps save energy. Select it by pressing the operating mode button if parameter P02 is set accordingly, or if the external operating mode switchover contact is active (e.g. window contact).

If the external operating mode switchover contact is active, user operations are ineffective and OFF is displayed. Control will then be according to Economy setpoints (P11 and P12).

In Protection mode, the system is – protected against frost (factory setting 8 °C (46 °F), can be disabled or changed via

P65)

– protected against overheating (factory setting OFF, can be enabled or changed via

P66).

In Auto Timer mode

, the thermostat automatically changes from Comfort to

AUTO

Economy mode according to the 8 preprogrammed timers. The display shows the Auto Timer mode symbol

along with the symbol for the

AUTO

current operating mode (Comfort or Economy ). Automatic is the default fan speed in Auto Timer mode.

Auto Timer function can be disabled with parameter P02 = 3, 4 or via DIP switch 5 on RDG160T..

Operating mode button

The behavior of the operating mode button can be selected via parameter P02:

4.3 Room temperature setpoints

Economy

mode

Comfort mode

Temporary setpoint

Setpoint limitation

P09 < P10 (comfort concept)

Example Cooling setpoint adjustable 18…25 °C (64…77 °F)

The factory setting for the Comfort basic setpoint is 21 °C (70 °F) and can be changed via parameter P08.

The setpoint in Comfort mode can be adjusted via the rotary knob.

If the "Temporary setpoint function" is enabled via parameter P69, the setpoint adjusted via the rotary knob is set back to the Comfort basic setpoint when the operating mode changes.

For comfort or energy saving purposes, the setpoint setting range can be limited to minimum (P09) and maximum (P10).

· If the minimum limit P09 is set lower than the maximum limit P10, both heating and

cooling are adjustable between these 2 limits.

· The customer adjusts the desired setpoint and the thermostat controls the room

temperature accordingly.

· For 4-pipe applications*), the selected comfort setpoint is in the middle of the dead

zone (P33). The unit stops to energize the heating/cooling outputs as soon as the room temperature reaches the dead zone.

Heating setpoint adjustable 18…25 °C (64…77 °F)

P09 ≥ P10 (energy saving concept)

Example

· If the minimum limit P09 is set higher than the limit P10, then

– The setting range of cooling setpoint is from P09…40 °C (P09…104 °F) in place of 5…40 °C (41…104 °F) – The setting range of heating setpoint is from 5…P10 °C (41…P10 °F) in place of 5…40 °C (41…104 °F) This allows the user to limit the maximum heating setpoint and the minimum cooling setpoint. This concept helps to save energy costs.

· For 4-pipe applications:

– The thermostat runs with the setpoint of the active sequence:

In heating mode, the heating setpoint is active and adjustable via rotary knob. In cooling mode, the cooling setpoint is active and adjustable via rotary knob.

– Switching from the heating setpoint to the cooling setpoint and vice-versa

occurs when the room temperature reaches the adjusted limitation (P09 or P10) of the inactive sequence. E.g. the thermostat is in heating sequence and runs with the heating setpoint. When the room temperature reaches P09, the thermostat switches to cooling mode and runs with the cooling setpoint, as long as the room temperature does not drop below P10.

Cooling setpoint adjustable 25…40 °C (77…104 °F) Heating setpoint adjustable 5…21 °C (41…70 °F)

Use control parameters P11 and P12 to adjust the Economy mode setpoints. The heating setpoint is factory-set to 15 °C (59 °F), and the cooling setpoint to30 °C (86 °F).

Use control parameters P65 and P66 to adjust the Protection mode setpoints. The heating setpoint is factory-set to 8 °C (46 °F) (frost protection) and to OFF for cooling.

Caution

If a setpoint is set to OFF (P65, P66), the thermostat does not maintain the setpoint in the corresponding mode (heating or cooling). This means no protective heating or cooling function and thus risk of frost in the heating mode or risk of overtemperature in cooling mode!

The Economy setpoints are accessible at the service level (P11, P12); the Protection setpoints at the expert level (P65, P66).

4.4 Setpoints and sequences

4.4.1 2-pipe and 2-stage applications

On changeover applications, the Comfort setpoints for heating and cooling sequence are the same (w).

On 2-pipe applications with electric heater, the Comfort setpoint is either at the first heating sequence (in heating mode) or at the cooling sequence (in cooling mode).

On 2-pipe applications with radiator, the Comfort setpoint is either at the radiator sequence (in heating mode) or at the cooling sequence (in cooling mode).

The setpoints for Economy and Protection mode are below the Comfort setpoints (heating) and above the Comfort setpoints (cooling). They can be set via parameters P11, P12 (Economy mode) and P65, P66 (Protection mode).

4.6 Additional features

cooling

Automatic heating/cooling changeover

Remote heating/ cooling changeover

The water temperature acquired by the changeover sensor (QAH11.1 + ARG86.3) is used to change over from heating to cooling mode, or vice versa.

· When thewater temperature is above 28 °C (82 °F) (adjustable via parameter

P37), the thermostat changes over to heating mode. It stays in heating mode until the temperature falls below 16°C (61 °F) (adjustable via parameter P36)

· When thewater temperature is below 16 °C (61 °F) (P36), the thermostat changes

over to cooling mode. It stays in cooling mode until the temperature rises above 28°C (82 °F) (P37).

· If the water temperature is between the 2 changeover points immediately after

power-up (inside the hysteresis), the thermostat starts in previous mode. The water temperature is acquired at 30-second intervals and the operating state is updated accordingly.

M Operating mode Cooling mode

Tw Water temperature Heating mode

The QAH11.1 cable temperature sensor for automatic heating/cooling changeover can be replaced by an external switch for manual, remote changeover:

Note

Manual heating/ changeover

External/return air temperature sensor

Contact open à heating mode Contact closed à cooling mode

The sensor or switch can be connected to input terminal X2 (factory setting) or X1 or D1 (switch only), depending on the commissioning of the inputs (P38, P40, P42). See also section 4.10 for details. The commissioning of the parameter Operating action (P39, P41, P42) has in this case no effect. The assignment is fixed: Contact open à heating mode

Contact closed à cooling mode

· Manual heating/cooling changeover means selection via changeover button on the

thermostat by repeatedly pushing the button until the required mode is shown on

the display (automatic changeover is done via an external sensor/switch connected

to X1, X2, or D1)

· If manual heating/cooling changeover is commissioned (P01 = 2), then

heating/cooling mode cannot be changed via changeover sensor/switch; it will

remain in the last mode as selected locally via button.

The thermostat acquires the room temperature via built-in sensor, external room temperature sensor (QAA32), or external return air temperature sensor (QAH11.1) connected to multifunctional input X1 or X2. Inputs X1 or X2 must be commissioned accordingly. See section 4.10.

Purge function

19/80

Siemens RDG100.., RDG110.., RDG160T.. Basic Documentation CE1P3181en Smart Infrastructure 2019-07-05

The changeover sensor ensures changeover from heating to cooling mode based on the acquired water temperature. We recommend activating the purge function (parameter P50) with 2-port valves. This function ensures correct acquisition of the medium temperature even if the 2-port valve is closed for an extended period of time. The valve is then opened for 1 to 5 minutes (adjustable) at 2-hour intervals during off hours. This function is available on all RDG variants for applications 2-pipe changeover and on RDG160T.. also for the 4-pipe changeover.

Caution

Avoid damage from moisture

Minimum output on-time/off-time

Floor heating/ Floor cooling

The purge function (parameter P50) must be disabled if the thermostat is used in compressor-based applications.

In very warm and humid climates, the fan can be run periodically or continuously at a low fan speed (e.g. in empty apartments or shops) in Economy mode by setting parameter P61, in order to avoid damage from moisture due to lack of air circulation. See also section 4.9 for details.

Limit the On/Off switching cycle to protect the compressor and reduce wear and tear. The minimum output on-time and off-time for On/Off control output can be adjusted from 1 to 20 minutes via parameters P48 and P49. The factory setting is 1 minute. Readjusting the setpoint or heating/cooling mode changeover immediately results in calculation of the output status; output Y11/Y21 may not hold the minimum 1-minute On/Off time. If parameter P48 or P49 is set to above 1 minute, the minimum On/Off time for the control output is maintained as set, even if the setpoint or changeover mode is readjusted. This function is only available for On/Off control with RDG100, RDG100T, RDG110.., and RDG160T...

All heating sequences can also be used for floor heating. You can use fan coil heating/cooling sequences for floor heating or cooling by disabling the fan via parameter P52.

Floor temperature limitation function

Recommended values for P51:

The temperature should be limited for 2 reasons: comfort and protection of the floor. The floor temperature sensor, connected to multifunctional input X1 or X2, acquires

the floor temperature. If the temperature exceeds the parameterized limit (parameter P51), the heating valve is fully closed until the floor temperature drops to a level 2 K (4 °F) below the parameterized limit. This function is factory-set to OFF (disabled). Input X1 or X2 must be commissioned accordingly (P38 or P40 = 1). See section 4.10 for details.

Living rooms: Up to 26 °C (79 °F) for long-term presence, up to 28 °C (82 °F) for short-time presence. Bath rooms: Up to 28 °C (82 °F) for long-term presence, up to 30 °C (86 °F) for short-time presence.

Note

Supply air temperature limitation (RDG160T..)

Dewpoint monitoring

Either floor temperature sensor or external room temperature sensor can be used.

This function increases the comfort in the room by keeping the supply air temperature of the fan coil unit between the selected minimum and maximum temperature limits. If the supply air temperature exceeds a limit, the thermostat reduces the corresponding valve position until the supply air temperature is back in the limits.

In case the air flow is too low (especially with DC 0...10 V fans), this prevents cold air from dumping into the room/warm air from bubbling straight up instead of circulating.

To enable this function, the multifunctional input, to which the supply air sensor is connected, needs to be set to "Supply air sensor" (e.g. P38=9). Then the parameters for the limits are visible (P63: minimum supply air temperature, P64: maximum supply air temperature).

This function is only active in Comfort mode and can only be used with DC 0...10 V actuators.

For applications with electric heater and radiator, this function is available only on the cooling valve (in cooling mode).

Dewpoint monitoring is essential to prevent condensation on the chilled ceiling (cooling with fan disabled, parameter P52). It helps avoid associated damage to the building. A dewpoint sensor with a potential-free contact is connected to multifunctional input X1, X2 or D1. If there is condensation, the cooling valve is fully closed until no more condensation is detected, and the cooling output is disabled temporarily. The condensation symbol is displayed during temporary override. The input must be commissioned accordingly (P38, P40, P42). See section 4.10.

The left button switches the operating mode from Economy to Comfort for the period preset in P68, if the following conditions are fulfilled:

· The operating mode switchover contact is closed (connected to input X1, X2, D1, parameter P38, P40, P42 set to 3)

· Parameter P68 (extend Comfort period) is greater than 0

During the temporary Comfort mode extension, sandglass symbol appears. If parameter P68 (extend Comfort period) = 0, extended Comfort cannot be activated;

pressing the left button will show "OFF" (blinking 3 times).

The current operating mode can be forced temporarily into Comfort or Economy/Protection mode. The time period is adjusted via the rotary knob:

· Extend presence: Set the device to Comfort mode for the selected time period

· Function on Q3, set parameter P74. Test relay function via diagnostic d10.

Notes

Switch OFF external equipment in Protection mode

Switch ON contact during Heat/Cool demand

· Those functions are available when DIP4 is set to OFF (EC fan).

· It is not suggested to use those functions in combination with the On/Off valve

control (P46/P47=1) to guarantee the temperature accuracy. If this combination is requested, the total maximum current on the relay outputs (Q1+Q2+Q3) should not exceed 2A.

The external equipment (such as: fan coil unit) can be switched OFF via relay output, in order to reduce energy consumption when the thermostat is in Protection mode and no temperature control is requested.

The function can be enabled by setting the corresponding Qx- parameter to 1. Relay contact is open when the thermostat is in protection mode.

During the heating or cooling demand, the relay contact can be energized to control an external equipment, for example to run the pump of a water system (fan coil).

To reduce the wear and tear of the HVAC equipment, the minimum output on-time and off-time of the Qx- relay output can be adjusted from 1 to 20 minutes via parameters P48 and P49. The factory setting is 1 minute.

The relay output remains OFF if the heating is provided ONLY by electric heater (application 2-pipe electric heater, heating by electric heater, cooling by fan coil) or radiator.

2-pipe water system (with one pump):

· Enable the function by selecting the corresponding output parameter to 2

· Connect the external equipment to selected relay output

· In case of heating/cooling demand, the output contact is energized

4-pipe water system (with two pumps):

· The function can be enabled by selecting the correspondent output parameters > set one parameter to 3. The output is energized during heating demand > set one other parameter to 4. The output is energized during cooling demand

· Connect the external equipment to the selected relay outputs

Output heating/cooling sequence

This function switches the relay output depending on the sequence, either heating or cooling. The output can be used for the release of a heat pump compressor.

· When the thermostat is in heating mode (even in dead zone): > the correspondent Qx- output contact is closed.

· When the thermostat is in cooling mode (even in dead zone): > the correspondent Qx- output contact is open.

The function can be enabled by setting the corresponding Qx- parameter to 5.

Heating or cooling with auxiliary heater

Electric heating, active in cooling mode

Note

Electric heating in heating mode

Electric heating and manual changeover

Digital input "Enable electric heater"

On 2-pipe applications with electric heater, the thermostat controls a valve in heating/cooling mode with changeover, heating only, or cooling only plus an electric heater. Cooling only is factory set (P01=1) with enabled electric heater (P13).

In cooling mode, the valve receives an OPEN command if the acquired temperature is above the setpoint. The electric heater receives an ON command if the acquired room temperature drops below "setpoint" minus "dead zone" (= setpoint for electric heater) while the electric heater is enabled (parameter P13 = on).

"Setpoint for electric heater" is limited by parameter "Maximum setpoint for Comfort mode" (P10).

In heating mode, the valve receives an OPEN command if the acquired temperature is below the setpoint. The electric heater is used as an additional heating source when the heating energy controlled by the valve is insufficient. The electric heater receives an ON command, if the temperature is below "setpoint" minus "setpoint differential" (= setpoint for electric heater).

The electric heater is active in heating mode only and the control output for the valve is permanently disabled when manual changeover is selected (P01=2).

Remote enabling/disabling of the electric heater is possible via input X1, X2 or D1 for tariff regulations, energy savings, etc. Input X1, X2, or D1 must be commissioned accordingly (parameters P38, P40, P42). See section 4.10.

On/Off control

On 2-pipe applications with radiator, the thermostat controls a valve in heating/cooling mode with changeover, heating only, or cooling only plus a radiator valve. Cooling only is factory-set (P01=1).

In cooling mode, the valve receives an OPEN command if the acquired temperature is above the setpoint. The radiator receives an ON command if the acquired room temperature drops below "setpoint" minus "dead zone" (= "setpoint for radiator").

In heating mode, the radiator receives an OPEN command if the acquired temperature is below the setpoint. The fan coil unit is used as an additional heat source when the heat energy controlled by the radiator is insufficient. The fan coil unit receives an ON command if the temperature is below "setpoint" minus "setpoint differential" (= setpoint for fan coil unit).

4-pipe application with manual changeover

"Main and secondary" application (4-pipe with changeover)

On 4-pipe applications, the thermostat controls 2 valves in heating and cooling mode, heating/cooling mode by manual selection, or heating and cooling mode with changeover. Heating and cooling mode (P01=4) is factory-set.

The heating or cooling output can be released via operating mode button if parameter P01 is set to manual (P01=2).

If parameter P01 is set to changeover (P01=3), the heating and cooling output is swapped according to the changeover sensor input status (see automatic heating and cooling changeover sensor, section 4.6). This mode is used for the so-called "Main and secondary" application. This is a 4-pipe fan coil unit system with different capacity of the 2 coils. The water circuit is changed to optimize the energy exchange depending on the season (summer/winter): – Winter: Large coil (V1) for heating, small coil (V2) for cooling – Summer: Large coil (V1) for cooling, small coil (V2) for heating

Adaptive temperature

mpensation for electric

co heater (RDG160T.., RDG110..)

When an electric heater is connected directly to the On/Off output (RDG160T..: Q2, RDG110..:Y21), the current causes the relay contact to heat up. This falsifies the reading of the internal temperature sensor. The thermostat compensates the temperature if the rated current/power of the electric heating is entered in the parameters.

RDG160T..: P45 (power electric heater): Factory setting: 0.0 kW, setting range: 0.0…1.2 kW.

RDG110: P46 (load current electric heater): Factory setting: 1 A, setting range: 1…5 A.

RDG110U: P46 is not available for AC 24 V operating voltage with electric heater controlled via external relay.

3-position control signal

Synchronization

PWM control

This function is available with RDG100 and RDG100T. Heating: Output Y1 provides the OPEN command, and Y2 the CLOSE command to

the 3-position actuator. Relay function Y1/Y2 and wiring can be tested via diagnostic parameter d05. Cooling: Idem with Y3 and Y4. Relay function Y3/Y4 and wiring can be tested via diagnostic parameter d06. The factory setting for the actuator's running time is 150 seconds. It can be adjusted via parameters P44 (Y1 and Y2) or P45 (Y3 and Y4). The parameters are only visible if 3-position is selected via DIP switches 4 and 5.

1. When the thermostat is powered up, a closing command for the actuator running time + 150% is provided to ensure that the actuator fully closes and synchronizes to the control algorithm.

2. When the thermostat calculates the positions "fully close" or "fully open", the actuator's running time is extended + 150% to ensure the right actuator position is synchronized to the control algorithm.

3. After the actuator reaches the position calculated by the thermostat, a waiting time of 30 seconds is applied to stabilize the outputs.

This function is available with RDG100 and RDG100T. The demand calculated by PI control from the current room temperature and setpoint

is provided via Y1 and Y3 to the valve actuator as a PWM signal (pulse width modulation) for thermal actuators. The output is activated for a period proportional to the heating/cooling demand and then switched off for the rest of the PWM interval.

The interval is 150 seconds (factory setting). It can be adjusted via parameters P44 (Y1) or P45 (Y3). These parameters are only visible if 2-position is selected via DIP switches 4 and 5 and if PWM is selected via P46 and P47.

Note!

PWM for thermal valve

For PWM, the integral time (P35) must be set to 0.

For thermal valve actuators, set the running time to 240 seconds.

Note!

· Never apply PWM to an electromotoric actuator.

· It is not possible to ensure exact parallel running of 2 or more thermal valve

The demand calculated by PI control from the current room temperature and setpoint is provided via Y10 and Y20 to the valve actuator as a continuous DC 0...10 V signal.

For applications with 3-speed fan, the electric heater can be controlled only via DC output.

· The demand calculated by PI control from the current room temperature and setpoint is provided via Y20 as a continuous DC 0...10 V signal.

· The signal converter (SEM61.4) converts the DC 0...10 V signal to AC 24 V PDM pulses for the current valve.

· The current valve (SEA45.1) supplies the electric heater with AC 50…660 V pulsed current.

For applications with ECM fan (DC signal) on RDG160T.., the electric heater can be controlled via the On/Off output (Q2) by setting P47 = 1. Adaptive temperature compensation: see 4.7.4.

Note: The control signals "Heating" and "Cooling" are not influenced by the manual setting of fan speeds.

By heating only with electric heater, manual fan speed 1 I cannot be selected to guarantee the necessary minimum air flow for the electric heater and to avoid overheating of the system.

For heating or cooling with 2 sequences (e.g. heating with a heating coil and an electric heater, or 2-stage cooling), the fan is always synchronized with the first sequence.

Fan operation can be limited to be active with cooling only or heating only, or even be totally disabled via control parameter "Fan operation" P52. When fan operation is disabled, the fan symbol on the display disappears and pressing the fan button has no impact. This function allows you to use the thermostat on universal applications such as chilled/heated ceilings and radiator, etc. (see section 4.7.9).

t [h:mm]

Fan minimum on- time

In automatic mode, a dwelling time of 2 minutes (factory setting) is active. The fan maintains each speed for at least 2 minutes before it changes to the next speed. This minimum on-time can be adjusted from 1…6 minutes via parameter P59.

Fan kick P60, P61

Note

Fan operation in dead zone P15

In automatic fan mode and with the room temperature in the dead zone, the control valve is normally closed and the fan disabled. With the "Fan kick" function, the fan can be released from time to time at low speed for minimum on-time (see above) even if the valve is closed.

This function can be used to avoid damage from moisture due to a lack of air circulation, or to allow a return air temperature sensor to acquire the correct room temperature.

Periodic fan kick Minimum

on-time

Periodic fan kick Minimum

on-time

The periodic fan kick time can be selected individually for Comfort mode via parameter P60, and for Economy mode via parameter P61.

· Fan kick value "0" means the fan runs continuously in the dead zone.

· Fan kick value “1” and higher: value in minutes

· Fan kick value "OFF" means the fan does not run in the dead zone.

Via parameter P15 in "Service Level", the fan speed in the dead zone (in Comfort mode) can be set according to customer preference. The following options are available:

· Fan does not run in the dead zone (P15=0)

· Fan runs at low speed in Heating and Cooling mode (P15=1)

· Fan runs at low speed in Cooling mode only (P15=2)

Fan start

Fan overrun for electric heater

The functions "Fan in dead zone" (P15) and "Fan kick" (P60) are combined as follows:

· P60 = 0 Fan runs continuously in the dead zone, P15 has no influence

· P60 = OFF Fan operation in dead zone according to P15

When the fan starts from standstill, it starts at speed 3 III for 1 second to ensure safe fan motor start by overcoming inertia and friction (selected via parameter P58).

1 sec

3181D22

When the electric heater is switched off, the fan overruns for 60 seconds (parameter P54) to avoid overtemperature of the electric heater or prevent the thermal cutout from responding.

45/80

Siemens RDG100.., RDG110.., RDG160T.. Basic Documentation CE1P3181en Smart Infrastructure 2019-07-05

Fan failure

In case of fan failure, the thermostat cannot protect the electric heater against overtemperature. For this reason, the electric heater must feature a separate safety device (thermal cutout).

Clean fan filter reminder

Fan in Auto Timer mode (RDG1..T)

Fan start delay

The "Clean fan filter reminder" function counts the fan operating hours and displays message "FIL " to remind the user to change/clean the fan filter as soon as the

threshold is reached. This does not impact the thermostat's operation, which continues to run normally. The function is set via parameter P62 (default = Off (0)). The "Clean filter reminder" is reset when the operating mode is manually set to Protection and back.

In Auto Timer mode , the default fan mode is automatic. The fan mode can be changed to Manual by pressing the FAN button. The fan returns to the automatic default mode after each switchover from Comfort to Economy mode, and vice versa.

To let the heating/cooling coil reach its temperature, the fan start can be delayed by a time period set via parameter P67.

4.12 Handling faults

Temperature out of range

Fault "Er1" on display

When the room temperature is outside the measuring range, i.e. above 49 °C (120 °F) or below 0 °C (32 °F), the limiting temperatures blink, e.g. "0 °C (32 °F)" or "49 °C (120 °F)". In addition, the heating output is activated if the current setpoint is not set to "OFF", the thermostat is in heating mode and the temperature is below 0 °C (32 °F). For all other cases, no output is activated.

The thermostat resumes Comfort mode after the temperature returns to within the measuring range.

When the built-in sensor fails and no external sensor is connected, the thermostat shows the fault message "Er1" on the display. The thermostat needs to be replaced if the room temperature needs to be measured with the built-in sensor.

4.13 Infrared remote control

5 Handling

5.1 Mounting and installation

Do not mount on a wall in niches or bookshelves, behind curtains, above or near heat sources, or exposed to direct solar radiation. Mount about 1.5 m (5 feet) above the floor.

Mounting

Wiring

· The room thermostat must be mounted in a clean, dry indoor place and must not be exposed to drip or splash water.

See Mounting Instructions (M3181.. or M3183..) enclosed with the thermostat.

· Comply with local regulations to wire, protection and earth the thermostat.

Warning! No internal line protection for supply lines to external consumers (Q1, Q2, Q3, Yx or Yxx)

Risk of fire and injury due to short-circuits!

· Adapt the line diameters as per local regulations to the rated value of the installed overcurrent protection device.

· The AC 230 V mains or AC 24 V supply line must have a circuit breaker with a rated current of no more than 10 A. For AC 24 V US installations, use Class 2 rated power supplies.

· Properly size the cables to the thermostat, fan and valve actuators for AC 230 V mains voltage.

· Use only valve actuators rated for AC 230 V on RDG100.., RDG110 and on RDG160T if AC 230 V is connected to the "L" terminal.

· Use only 3-speed fan rated with AC 24 V on RDG160TU.

· Isolate the cables of inputs X1-M/X2-M and D1-GND if the conduit box carries

AC 230 V mains voltage.

· On the RDG100.. and RDG110, inputs X1-M and X2-M carry mains potential. If the sensor’s cables are extended, they must be suited for mains voltage.

· Inputs X1-M, X2-M or D1-GND of different units (e.g. summer/winter switch) may be connected in parallel with an external switch. Consider overall maximum contact sensing current for switch rating.

· Selectable relay function (RDG160T..). Consider overall maximum current though the relays.

· Disconnect power supply before removing the thermostat from the mounting plate!

Commissioning

(Only for

1. Select the application via the DIP switches at the rear of thermostat before fitting the front panel to the mounting plate.

2. Power up the thermostat after successfully connecting the line power. The thermostat starts to reset and all LCD segments flash, indicating that the reset is correct.

After the reset, which takes about 3 seconds, the thermostat is ready for commissioning by qualified HVAC staff. The control parameters of the thermostat can be set to ensure optimum performance of the entire system (see section 4.15).

Notes

Control sequence

Compressor-based application

Calibrate sensor

Adaptive temperature compensation for electric heater

The temperature unit selection wizard enables to select the preferable temperature unit display on thermostats between °C and °F.

1. Rotate rotary knob to select the preferable temperature unit to be displayed and operated.

2. Confirm the selection by pressing button (OK), which leads the thermostat advance to normal operating page.

· Pressing button (Esc) does not confirm the temperature selection.

· If the temperature unit is not selected, °C is used by default.

· The control sequence may need to be set via parameter P01 depending on the

application. The factory setting for the 2-pipe application is "Cooling only"; and "Heating and cooling" for the 4-pipe application.

· When the thermostat is used in connection with a compressor, the minimum output

on-time (parameter P48) and off-time (parameter P49) for Y11/Y21 must be adjusted to avoid damage to the compressor and shortening its life.

· Recalibrate the temperature sensor if the room temperature displayed on the

thermostat does not match the room temperature measured. To do this, change parameter P05.

· When an electric heater is connected directly to output Y21, the rated current of the

electric heating should be entered in parameter 46 (RDG110 only, device index D and higher), see section 4.8. Default setting: 1 A for loads £ 1 A.

Setpoint and setpoint setting range limitation

· We recommend to review the setpoints and setpoint setting ranges (parameters

P08…P12) and change them as needed to achieve maximum comfort and save energy.
