3. Set the remote thermostat to a temperature above the ambient room temperature
by turning the knob. NOTE: The heater will start only if the thermostat “calls for
heat” meaning that it is set to higher than prevailing ambient temperature.
4. Select the power range by means of the switches marked S1....S3
S1 on = 16 kW = 51,200 BTUH (S2 & S3 off)
S1 & S2 on = 32 kW = 102,400 BTUH (S3 off)
S1 & S2 & S3 on = 40 kW = 136,500 BTUH
The heater will now operate automatically, controlled by the thermostat.
