5.7 Electrical connection
The hydraulic connection of the device to the water supply is followed by the electrical
connection. For connecting the device to the electricity the plug of the connecting cable has to
be plugged into a standard socket he commissioning procedure is described in chapter 6.
CAUTION
The device has no additional switch for commissioning, it will turn on immediately
after connecting it to the electricity grid. Before turning on the device it is necessary
to follow the instructions in chapter 6.
CAUTION
The connecting cable has a standard plug suitable for a standard socket (16 A;
230 V ac). This socket has to have its own power supply directly from the main
electrical cabinet. Other devices must not be connected to the same line.
6 Commissioning of the device
6.1 Filling the device with water
After an expert has connected the device to the water supply, the system has to be filled with
water and thoroughly vented. This is performed by opening all water taps in the residence.
When water flows uninterrupted from all taps, the system is thoroughly vented.
CAUTION
The device’s aggregate must never operate without water in the buffer tank for DHW.
6.2 Inspections before commissioning
Before commissioning, the following inspections must be performed on the device:
The buffer tank for DHW must be filled with water and thoroughly vented.
All hydraulic connections must be tightly sealed.
A suitable expansion tank and safety valve must be installed.
All safety elements must work.
6.3 Connecting the device to the electrical supply
The device is equipped with a standard connection cable. Before commissioning, the plug of
the connection cable has to be plugged into the standard socket 16 A, 230 V ac.
6.4 Commissioning of the device
After connecting the device to the electrical network, one of the switches on the left or right
side of the temperature display of the buffer tank for DHW has to be switched on and the
temperature on the main thermostat set in order to switch on the aggregate.
The device starts operating and operates until the set breaking temperature is reached. The
shut-down temperature is set with the main thermostat. After shut-down, the operation is
suspended until the water cools for 3 °C. When the water in the buffer tank for DHW reaches
this temperature, the device turns on again. The user can freely raise the set breaking
temperature but no more than 65 °C (restriction of the main thermostat) or freely lower it.
NOTE
The device operates with intake air from approx. +10 °C to approx. 35 °C
(depending on relative moisture).
