USER GUIDE
Dual Sensing Digital Thermostat 230Vac WFHT 041 (20425)
MODES DESCRIPTION
-
Electronic thermostat with LCD display mode for water floor heating
systems controlled by actuators.
-
External pilot wire for night reduction.
-
Three Functioning modes: Comfort, reduction or Clock mode.
-
Possibility to regulate either the floor or room temperature, or combined
(in this case, the floor sensor is used as temperature limiter)
-
Silent (triac output), to be connected directly to actuators (see connecting
drawing on the installation sheet) or to our Modular connecting system.
(In this case please refer to the connecting box datasheet)
Use OK key to change the mode in the Operating mode menu
COMFORT operating mode:
Force comfort temperature operation
indefinitely.
By pressing +/- keys the comfort
temperature starts to blink and can be
adjusted.
The measured
temperature
reappears after a few seconds.
OFF mode:
Use this mode if your Heating
installation needs to be turned OFF.
The display is blank.
(Careful in this mode your installation
can freeze)
Parameters are saved.
GB
REDUCED operating mode:
Force reduced temperature operation
indefinitely.
By pressing +/- keys the comfort
temperature starts to blink and can be
adjusted.
The measured
temperature
reappears after a few seconds.
External PILOT WIRE mode:
The Thermostat will follow the external
PILOT WIRE signal.
Blinking for indicate a comfort signal.
Blinking for indicate a reduced signal.
INSTALLATION PARAMETERS MENUS
Press the OK key during 5 seconds, Then use + or - keys to select the installation parameter to be adjusted.
Press OK to toggle the parameter setting or edit the value. If the value starts to blink you can use + / - keys to adjust
this value. Press + & - keys at the same time to reset this value to the factory default value. Once you have adjusted
the value press OK to validate this parameter value.
When you have finished, use + / - keys to go to 'End' display and then press OK key to exit installation parameter
menu.
