Supply
The power supply cable is connected at (1). Length 200 cm.
The group fuse is selected such that all relevant requirements for the
electrical installation are met; see technical data. The size of the fuse is set
in the installation flow on the touchscreen. The product adjusts the electrical
power according to this. Once a current sensor has been installed, the built-
in load switch is able to regulate the immersion heater's electrical output
based on the set main fuse.
Omnipolar safety switch
The installation should be preceded by an omnipolar safety switch according
to overvoltage category III, which ensures disconnection from all electric
power sources.
Residual current device
If there already is a ground fault breaker, the product must also be fitted with
its own ground fault breaker with on/off delay.
Max thermostat
If the product has been stored in an extremely cold place, the max.
thermostat may have been triggered. Reset it by pressing in the button
on the electrical switchboard behind the front panel. Always check on
installation that the max thermostat has not tripped.
Extra low voltage protection
The following outputs and inputs have extra low voltage protection: current
transformer, outdoor sensor, room sensor, primary flow sensor, return
sensor, NR/SO.
Accessory: expansion card (A3)
For certain system options the product must be supplemented with the
expansion card accessory (A3). See the manual provided for how to install
the card. Settings which are entered after installation are found in this
