Operating Modes:
The heater is designed to function in two different operating modes.
“Water Temp” mode allows you to control the maximum engine coolant temperature that the
heater will maintain. This is the most common operating mode. This mode allows you to set the
desired maximum operating temperature from 30
ºC
to 75
ºC
. While operating in this mode, the
heater will switch on and off according to the requirements to maintain the desired maximum
temperature.
“Automatic Climate - A/C” mode allows you to control the maximum cabin temperature that the
heater will maintain. This is a less common operating mode and is only practical for use with cargo
and cabin heating applications. This mode allows you to set the maximum cabin temperature from
14
ºC
to 40
ºC
(As measured at the Control Switch). In this mode the heater will maintain a coolant
temperature between 60
ºC
and 75
ºC
. However, once the maximum cabin temperature is reached,
the heater will go into standby mode.
When heater is initially started for the first time it will start in “WaterTemp” Mode. Subsequent starts
will be in the last used mode “WaterTemp” or “ A/C”
Switching Between Operating Modes (Heater Must Be Running):
To switch heater between “WaterTemp” Mode and
“A/C” Mode;
Press. three times.
“WaterTemp” or “A/C” mode will be
