Heat transfer controller installation
1.1
Mounting
WARNING!
Electric shock!
Î
Always disconnect the device from power supply
before opening the housing!
Upon opening the housing, live parts are exposed!
The FC4.13 DHW controller is integrated into the SUS Midi or Maxi heat transfer
module respectively. If the controller is to be installed outside of the heat transfer
module, please mind the following instructions. The device must only be located
in dry interior rooms. The controller must additionally be supplied from a double
pole switch with contact gap of at least 3 mm.
Please pay attention to separate routing of sensor cables and mains cables.
In order to mount the device to the wall, carry out the following steps:
Î
Unscrew the cross-head screw from the cover and remove it along with the
cover from the housing
Î
Mark the upper fastening point on the wall. Drill and fasten the enclosed wall
plug and screw leaving the head protruding.
Î
Hang the housing from the upper fastening point and mark the lower fastening
points (centres 150 mm).
Î
Insert lower wall plugs.
Î
Fasten the housing to the wall with the lower fastening screw and tighten.
Î
Carry out the electrical wiring in accordance with the terminal allocation, see
chap. 1.2.
Î
Put the cover on the housing.
Î
Attach with the fastening screw.

Note:
Strong electromagnetic fields can impair the function of the controller.
Î
Make sure the controller as well as the system are not exposed to
strong electromagnetic fields.
1.2
Electrical connection
WARNING!
Electric shock!
Î
Always disconnect the device from power supply be-
fore opening the housing!
L' is a fused contact permanently carrying voltage.
ATTENTION!
ESD damage!
Electrostatic discharge can lead to damage to electronic
components!
Î
Take care to discharge properly before touching
the inside of the device! To do so, touch a grounded
surface such as a radiator or tap.
The controller is equipped with 4 relays in total to which loads such as pumps,
valves, etc. can be connected:
Relays 1 … 3 are semiconductor relays, designed for pump speed control.
Relay 4 is a potential-free electromechanical relay.
Conductor R1 … R4
Neutral conductor N (common terminal block)
Protective earth conductor
⏚
(common terminal block)
Note:
Connecting the device to the power supply must always be the last step
of the installation!
Note:
In the heat transfer module with this controller, only high-efficiency
pumps with a PWM control signal can be used.
Note:
The minimum pump speed must be set to 100 % when non-speed-con-
trolled devices such as valves are connected.
