Calibrating the room temperature sensor of the Combi (D) (“OFFSET”) The room temperature sensor of the connected Combi (D) can be adjusted individually to suit the location of the sensor. Settings can be made in the range from 0 °F to -10 °F (0 °C to -5 °C) in 1 °F (0.5 °C) increments.

Example

Set room temperature 75 °F;
OFFSET = -1 °F;
Setpoint for Combi (D) = 74 °F
Default setting: 0 °F (0 °C).

AC SET

(Only available if ACC is set to “ON”)

The sensed room temperature can – during the operation of the automatic climate control – be perceived differently during cooling than during heating. “AC SET” is used to set an offset between cooling and heating. The setting can be made in increments of 1 °F (0.5 °C) within the range of 0 °F to 10 °F (0 °C to 5 °C).

Example

Set room temperature 74 °F;
AC SET = 2 °F
Setpoint value for air conditioning
system = 76 °F
Presetting: +2 °F (+1 °C).

ACC

(Only available if the air conditioning system and furnace are connected)

The automatic climate control function AUTO is activated or blocked with “ACC”.

ON: The automatic climate control function AUTO is activated. Automatic climate control function AUTO can be selected in the Room temperature menu. – “AC SET” appears in the Service menu.

IR remote control

Air conditioning systems – the shared use of IR remote control and CP plus

Even after connecting the CP plus, the IR remote control is still available to control the air conditioning system. The CP plus recognizes all settings (except dehumidification mode) that are made on the air conditioning system using the IR remote control. The IR remote control only transmits the settings that are shown in its display (no bidirectional communication).
Only the time switch of the CP plus may be used to clearly define the start and end time of a required period.

Maintenance

The CP plus is maintenance-free. To clean the front, you can use a non- abrasive cloth moistened with water (and a neutral soap solution).
