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.

Connections
The electrical energy meter is connected to the S0+/S0- input on the EHC–04 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 weight: between 1 and 1000 Wh
If the meter pulse weight is given in number of pulses/kWh, the pulse weight must be be
tween the following numbers: 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 hydraulic or electrical back-up is also
factored in to provide the full tally of restored thermal energy.
