Functions

Temperature control

RDH100RF/SET offers both 2-position and PID intelligent learning temperature control, configurable via parameter P01 (control behavior).
2-position control algorithm to switch on and off the heating system within a switching differential (SD) as per the difference between setpoint setting and measured room temperature.

PID intelligent learning control algorithm periodically switches on and off the heating system.
The period time (T) and pulse length (P) of the control signal (PWM) are determined by the setpoint and the measured room temperature.

In general, PID control provides more comfort and is more energy efficient than 2-position control.

Control behavior (P01)

The factory setting for control is “PID slow”, ideal for most heating systems. Optimum control can be selected if control does not provide the desired result:

2-position, 1 K
2-position controller with 1 [K] switching hysteresis

• For systems with small capacity that appear slow

• For applications requiring extended runtimes or where frequent switching causes problems

• For difficult control loops where hunting may result
  Typical applications:

• Dry floor heating systems

• Heat pumps

• Electric heating with contactors

2-position, 0.5 K

• 2-position controller with 0.5 [K] switching hysteresis.
• For general control situations. Provides better comfort than 1 [K] switching hysteresis.
• Can also be used for difficult control situations.

PID slow
PID control behavior for slow heating systems that require longer minimum On times and a limited number of switching cycles per hour.

Typical applications:

• Wet floor heating systems, oil fired boilers
• Can also be used for all other types of heating applications. (Alternative setting)

PID fast
PID control behavior for fast heating systems that tolerate a high number of switching cycles.

Typical applications:

• Electric heaters with current valve
• Gas boilers
• Fast thermal actuators

  WARNING

| Do not use PID fast for oil boilers or electric mechanical actuators!

Backup
When removing the batteries, the setpoints and information required for operating mode changeover are retained for max. 2 minutes.

Parameter list

Parameter| Description| Factory setting| Setting range| Remark
---|---|---|---|---
P01| Control behavior| PID slow (4)| 0 = 2P, 1.0 K

1 = 2P, 0.5 K

2 = PID fast 4 = PID slow

|
P02| Maximum temperature range| 30 °C| P03…30 °C| Limit of comfort and economy setpoint
P03| Minimum temperature range| 5 °C| 5 °C…P02| Limit of comfort and economy setpoint
End| Exit parameter setting| | |

Parameter setting
The parameter setting remains in non-volatile memory and is not erased when the battery is removed. The reset function on the rear of the thermostat reloads the factory settings.

|

Parameter setting mode

1.    Press LEARN on the rear for 5 seconds until “P01”

appears.

2.    Press LEARN again and, the parameter value on the second line flashes and is ready for adjustment.

3.    Adjust the parameter using setting knob.

4.    Press LEARN once to confirm the setting.

5.    Rotate the setting knob clockwise to next parameter and repeat steps 2 to 4.

6.    Exit parameter setting mode by rotating the setting knob

clockwise to “End” and pressing LEARN once.

Note: The thermostat automatically exits parameter setting mode one minute after the last action.

Display
The digital display shows the current room temperature and the comfort temperature setpoint. When the heating output is active, the triangle symbol is displayed.

Ordering

When ordering, specify both name and product number, e.g. room temperature controller RDH100RF/SET.
Order valves and actuators as separate items.

Mechanical design

The transmitter consists of 4 parts:

• Plastic housing with digital display containing the electronics, operating elements and built-in room temperature sensor
• Baseplate (mounting base)
• Battery compartment
• Fold-out stand
  The housing engages in the baseplate and snaps on. There is a reset button on the rear of the transmitter.

Elements| 1| | Display of the room temperature in

°C / °F

---|---|---|---
2| | Indicates a request for heating
3| | Temperature setting knob
4| | Battery compartment
5| | Comfort temperature setpoint
6| | Indicates RF signal test
7| | Indicates low battery power; replace batteries

The receiver is located in a plastic housing with LEDs and buttons.

The transmitter is located in a plastic housing. Two buttons are visible on the rear when removing the baseplate.

OVERRIDE

Override allows for temporarily overriding the active value from the sender. Override responds differently depending on the radio connection (normal or fault).

Example A: Normal connection between sender and receiver
Press the OVERRIDE button to overwrite the value for ca. 14 minutes. The value then returns to the setpoint.

Example B: Faulty connection between sender and receiver
Press the OVERRIDE button to permanently override the value. The value returns to the setpoint after the connection between sender and receiver works again.

Mounting

DANGER

Electric shock on directly touches of EMI filter

• Disconnect from power supply before connecting EMI filter.
• Make sure EMI filter is out of reach after installation.
  If the reference room contains thermostatic radiator valves, set them to their fully open position.

For commissioning, refer to the operating instructions A6V101035988.
Communication of the RDH100RF/SET (transmitter and receiver) is paired ex factory.

• The devices are suitable for wall mounting.
• Recommended height: 1.5 m above the floor.
• Do not mount the devices in recesses, shelves, behind curtains or doors, or above or near heat sources.
• Avoid direct solar radiation and drafts.
• Seal the conduit box or the installation tube if any, as air currents can affect sensor readings.
• Adhere to allowed ambient conditions.

Change of batteries
If the battery symbol appears, the batteries are almost empty and must be replaced.

Reset
Simultaneously press the TEST and LEARN buttons on the rear of the transmitter to reset it.
Simultaneously press the OVERRIDE and LEARN buttons to reset the receiver. This resets all individual settings to their default values.

Maintenance
The transmitter and receiver are maintenance-free except for the transmitter battery.

Disposal

This symbol or any other national label indicate that the product, its packaging, and, where applicable, any batteries may not be disposed of as domestic waste. Delete all personal data and dispose of the item(s) at separate collection and recycling facilities in accordance with local and national legislation.
