2.2 Electrical connection
WARNING! Electric shock!
Upon opening the housing, live parts are exposed!
Î Always disconnect the device from power supply
before opening the housing!
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 sur-
face such as a radiator or tap!
Note
Connecting the device to the power supply must always be the last step
of the installation!
Note
It must be possible to disconnect the device from the power supply at
any time.
Î
Install the power supply plug such that it is accessible at any time.
Î If this is not possible, install a switch that can be accessed.
Do not use the device if it is visibly damaged!
The controller is supplied with power via a power supply cable. The power supply
of the device must be 115 V~.
The controller is equipped with 1 electromechanical relay to which a load such as
a pump, a valve, etc. can be connected
Relay 1
7 = normally open contact (RO)
8 = normally closed contact (RC)
9 = neutral conductor (N)
Grounding terminal
⌯
(common terminal block)
The power supply connection is at the terminals:
10 = neutral conductor (N)
11 = conductor (L)
Grounding terminal
⌯
(common terminal block)
Connect the temperature sensors (S1 and S2) to the corresponding terminals
with either polarity:
1 / 2 = Sensor 1 (e. g. collector sensor)
3 / 4 = Sensor 2 (e. g. tank sensor)
3 operation and function
3.1 Flashing codes
The operating control lamp indicates the current status of the controller.
Colour Permanent Flashing
Green Relay active Antifreeze function
3.2 Jumper and potentiometers
A
B
The jumper (A) can be used for activating or deactivating the antifreeze function.
With the potentiometer (B), the switch-on temperature difference can be adjusted
(in K).
