1. Open the user menu.
2. Select the room temp. correct. option.
3. Setting calibration of the room temperature: the “K” in the display stands for the Kelvin unit;
1 K corresponds to 1 °C. The basic setting is 0.0 K.
Example: if the thermometer displays a temperature 0.5 °C higher than the programming unit,
then enter “+0.5 K” as calibration value.
The result will be displayed immediately as the corrected room temperature.
5.17 Setting the preheating phase for a Loganova gas heat pump
With GHP preheat phase you can set a preheat phase for a gas operated heat pump (Loganova
GHP)
1)
. This setting is not relevant for other equipment.
During the preheating phase the gas booster of the gas heat pump preheats the heating system
without a peak load boiler. Generally, the permanent operation of the heat pump raises the overall
efficiency and saves more energy than in room temperature reduction mode. We therefore
recommend setting a preheating phase.
1. Open the user menu.
2. Select GWP preheat phase.
3. Setting preheat phase: set the desired duration (0.00 to 16:30, hours:minutes).
The preheating phase commences by the set time before the day mode of the first heating circuit
begins.
5.18 Setting energy price ratio for hybrid
Depending on the prescribed mode of the hybrid system with HM10 hybrid module, you can set the
energy price ratio here.
2)
A thermometer may indicate temperature fluctuations more slowly or rapidly than the
programming unit.
B Therefore, never calibrate the programming unit during phases when the heating
system is cooling down or heating up.
1) The function depends on the boiler used
You will achieve the highest efficiency if the heat pump with gas booster heater
operates constantly. For this, set the preheating phase so it is longer than the night
mode period of the current switching program.
2) This function is only available in association with the hybrid module and depends on the operating mode
of the hybrid system.
