When discomfort is experienced in domestic hot water mode, the installer
may adjust the domestic hot water production setting parameters to
increase domestic hot water comfort, to the detriment of heating comfort.
1. Adjust the following parameters:
On
Parameter
Hysteresis DHW
(DP120)
Min. CH before DHW
(DP048)
Max. DHW duration (DP047)
7.3.8
Configure the back-up boiler according to its control panel. Set the installer
parameters.
1. Switch the boiler control system to 24h/24 comfort mode.
2. Heating set point temperature = Domestic hot water set point
7.3.9
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.
Minimum admissible voltage: 27 V
Minimum admissible intensity: 20 mA
Minimum pulse time: 25 ms
Maximum frequency: 20 Hz
Pulse weight: between 1 and 1000 Wh
If the meter impulse weight is given in number of impulses/kWh, the impulse weight must
be between 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
automatically factored in by the control system to provide the full tally of
restored thermal energy.
Important
The consumption of electricity may rise.
