USER GUIDE
Thermostat basic with pilot wire 230Vac ANO WFHT 012 (20121)
Thermostat basic with pilot wire 230Vac ANC WFHT 013 (20122)
MODES DESCRIPTION
-
Electronic thermostat with night reduction mode for water floor
heating systems controlled by actuators.
-
External pilot wire for night reduction, equipped with a switch to
select comfort, reduction or clock mode.
-
Regulating on internal sensor.
-
Option: Possibility to regulate on external sensor (NTC 10K)
The external sensor must be connected without power supply.
At power up the thermostat automatically detects the sensor used.
(If the external sensor is connected the regulation use this sensor)
-
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)
