Does the display show HEAT ON in zone 1 / 2?
NO:
o The temperature is higher than SET TEMP. Adjust SET TEMP to higher temperature.
o The snow around the ground sensor is melting/drifting snow has exposed the sensor.
AFTERRUN time must be increased. Alternatively, FORCED HEAT can be activated.
o Igloo effect around the sensor. The ground sensor has melted an insulated hollow under the snow.
Activate FORCED HEAT or, alternatively, set MOIST SENSOR to OFF.
o The temperature is lower than the OFF TEMP setting.
Depending on dimensioning, the system has a lower temperature limit, at which the system can
melt the snow. Try melting the snow with FORCE HEAT, before OFF TEMP is changed.
The heat does not shut off after ice/snow melting
o Afterrun time is too long – reduce AFTERRUN time and activate RESTART in the menu.
o Moisture detection in the ETOG/ETOR sensor is turned off – set MOIST CTRL to ON in the menu.
