Operating modes fan heaters water
Set the maximum fan speed, heating step and
desired room temperature. The thermostat
is controlling the room temperature by
increasing/decreasing the fan speed. When
the desired room temperature is reached the
actuator/valve will close and the fan stops.
Maximum fan speed is limited to step 4.
If Parameter P04 is changed from 1 to 0 (see
list of parameters on next page) the fan runs
continuously on set speed and the thermostat
controls the heating on/off.
Heat regulation
When the room temperature drops below
the set point temperature the first heating
step is activated. If temperature continues to
drop, another heating step is activated (see
description below parameters P.00).
Heat regulation
When the room temperature drops below the
setpoint, the valve is opening for heat.
System on/off
Press the ON /OFF button for 2 seconds
to switch off the system. The unit's safety
functions are still active when the system is
switched off, which means that the fan can
continue to run for a while.
