Energy meter specifications
Minimum admissible voltage: 27 V
Minimum admissible intensity: 20 mA
Minimum pulse time: 25 ms
Maximum frequency: 20 Hz
Pulse weighting: between 1 and 1000 Wh
Choose meters whose impulse number per kW is a multiple of 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 fac
tored in to provide the full tally of restored thermal energy.
1. Go to the Installer menu.
2. Access the Installer menu: enter the code 0012 by pressing the
and keys.
3. Confirm access by pressing the
key.
4. Select EHC-04 by pressing the or key.
5. Confirm access by pressing the
key.
6. Configure the HP033, HP034 and HP035 parameters.
Tab.58
Situation
Configuration
According to the type of
energy meter installed
Adjust the impulse value of the HP033 parameter. The setting range of the HP033 parameter goes
from 0 (no metering) to 1000 Wh.
The default setting for the impulse weight is 1 Wh.
If the meter impulse weight is given in a number of impulses per kWh, divide this value by 1000.
If a hydraulic back-up is
fitted
Set the HP034 and HP035 parameters to 0.
If an electrical back-up
is fitted
Set the HP034 and HP035 parameters according to the configuration of the electrical back-up stages
output.
10.5.5 Configuring a hydraulic back-up
1. Configure the back-up boiler according to its control panel.
Configuring a boiler equipped with a room thermostat input
1. Set the following installer parameters on the boiler control panel.
