When the heating is sufficient and domestic hot water discomfort is
experienced, the installer may make the following adjustments:
Note that domestic hot water comfort is at the expense of heating comfort.
1. Reduce the set point temperature differential triggering the domestic
hot water tank to be charged: DP120 parameter.
Important
In this case, the electricity consumption is likely to increase.
2. Reduce the minimum heating duration between two domestic hot
water production runs DP048
3. Increase the maximum authorised duration for domestic hot water
production DP047.

domestic hot water, page 73

Improving heating comfort
The system does not allow the simultaneous production of heating and
domestic hot water.
When the domestic hot water temperature is sufficient and heating
discomfort is experienced, the installer may make the following

Connections
The electrical energy meter is connected to the S0+/S0- input on the EHC–05 PCB.
Do not install meters for the electrical back-ups.
Energy meter specifications
Minimum power supply voltage range: 24 V +/-10 %
Minimum admissible intensity: 20 mA
Minimum pulse time: 25 ms
Maximum frequency: 20 Hz
Pulse weighting: between 1 and 1000 Wh
If the meter pulse weight is given in a number of pulses per kWh, the pulse weight must be
one of the following values: 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 125, 200, 250, 500 or
1000.
Energy metering provides information on:
electrical energy consumption,
the production of thermal energy for heating, domestic hot water and
cooling modes.
The thermal energy from the electrical back-up is also factored in to
provide the full tally of restored thermal energy.
