Main components
1 Switch box
The switch box contains connection terminals for the power
supply and digital controller, and the main electronic and
electrical parts of the unit.
2 Main isolator switch
The main isolator switch allows to cut off all electrical power to
the unit.
3 Heat exchanger
4 Water inlet connection (1” MBSP)
5 Water outlet connection (1” MBSP)
6 Pump
The pump circulates the water in the water circuit.
7 Manometer
The manometer allows readout of the water pressure in the
water circuit.
8 Expansion vessel (6 litre)
The water in the water circuit expands with rising temperatures.
The expansion vessel stabilises the pressure changes with
changing water temperatures by giving free space to the
changing water volume.
9 Expansion vessel service point
The service point allows connection of a dry nitrogen cylinder to
adjust the expansion vessel pre-pressure if necessary.
10 Drain and fill valve (2x)
11 Air purge valve
Remaining air in the water circuit will be automatically removed
via the air purge valve.
12 Water filter
The water filter removes dirt from the water to prevent damage
to the pump or blockage of the evaporator. The water filter
should be cleaned on a regular base. See "Maintenance" on
page 13.
13 Water temperature sensors
Two temperature sensors determine the water inlet temperature
(13a) and water outlet temperature (13b).
14 Digital controller cable intake
15 Power supply intake
16 OP10 heater tape (optional, not illustrated)
The heater tape is wrapped around the pipework and protects
the evaporator and water circuit in the unit from freezing at cold
outdoor temperatures.
Safety devices
17 Flow switch
The flow switch checks the flow in the water circuit and protects
the heat exchanger against freezing and the pump against
damage. In case the minimum required flow is not achieved, the
unit will be shut down.
18 Pressure relief valve
The pressure relief valve prevents excessive water pressure in
the water circuit (≥3 bar).
Switch box components
19 Cable tie mountings
The cable tie mountings allow to fix the field wiring with cable
ties to the switch box to ensure strain relief.
20 Ter minal block
The terminal block allows easy connection of field wiring.
