optional accessory.

2. Install the heater in the heating water flow line (from the condenser) as indicated in
the piping diagram.
3. Set the heater’s internal thermostat to its highest setting (85 °C).

The heater has either 28 mm stainless steel pipes or 1" threaded connections.

another 1/2 turns with a wrench.
General instructions
When an in-line heater has not been installed and enabled in the automation system,
the standard position for fuse F2 is OFF.
If an in-line heater has been installed and it needs to be disabled, disable the heater
from the heat pump’s settings. If an in-line heater has been installed and enabled in the
settings, do not set the heater’s fuse to the OFF position, unless there is a fault in the
heater.
In units that come with the in-line heater preinstalled, the heater’s internal
thermostat should not be adjusted. The thermostat has been set to its highest
setting (approximately 85 °C) at the factory. The thermostat will shut off power to the
immersion heater only if there is a malfunction in the heat pump’s automation system.
If you have accidentally turned the thermostat knob, turn the knob back to its highest
setting.
The in-line heater is equipped with an internal overheat protection device. The device
shuts the heater’s power off when the internal temperature of the immersion heater
cartridge exceeds 110 °C. To reset the switch, press the button on the black connection
box on top of the heater. The button is under a transparent plastic lid. Remove the
plastic lid with a slot-head screwdriver. Before resetting the overheat protection device,
determine what caused the device to trip and address the issue. The device may have
tripped due to vibration during transport or relocation.
