Other important information or tips.
Safety Behavior and Practices
• Use the CPplusVarioHeat control panel
only when it is in a technically sound
condition.
• Have a specialist immediately remedy any
malfunctions. Remedy the malfunction
yourself only if a remedy is specified in the
troubleshooting chart in these operating
instructions.
• Have a defective CPplusVarioHeat control
panel repaired only by the manufacturer or
its service department.
• Any alteration to the appliance or its controls can be dangerous and will void the
warranty.
• Switch OFF the VarioHeat furnace and/or
AquaGo when refueling, pumping gas or
when the recreational vehicle (RV) is in a
parking garage, on a ferry, or in enclosed
spaces (such as a garage, repair shop).
Make absolutely sure that the VarioHeat
furnace and/or AquaGo cannot be switched
on via the time switch. To do this, you have
to switch the CPplusVarioHeat control
panel off or interrupt the power supply to
the control panel.

2.3 HARDN
1. Calibrating the room temperature sensor
of the heater (OFFSET)
The room temperature sensor of the connected
heater can be adjusted individually to suit the
location of the sensor. Settings can be made in
the range from 41°F to 23°F (5 °C to -5 °C) in
1°F (0.5 °C) increments.
Example:
Set room temperature 75 °F;
OFFSET = -1 °F;
Setpoint for heater = 74 °F
Fig. 17
Default setting: 0°F (0°C).
2. AquaGo
Available only when AquaGo is connected.
2.1 CALCI
The appliance must be decalcified
regularly depending on water hardness
and hot water consumption.
Specify the hardness of the water that is used.
