Compressor LED

This LED is not lit up when the compressor is not in operation.

in start-up time delay and will begin operation after

this time has elapsed. If this LED is continuously lit

up, the compressor is in operation. The time delay is no

longer active.

This LED is continuously lit up when the regulation is

connected to the power supply.

The fan board is connected to the CH–DIN regulation.

The CH-DIN (C2-DIN) regulation registers the current

condensation temperature via the sensor input ST 5 (ST

6) and passes along the corresponding programmed

output current to the CTK 1 (CTK 2) output of the TK 1

(TK 2) fan board.

The fan motor rotation can be controlled by the modulating

output current.

C2–DIN Additional Regulations for Models RKW 3600

and higher

For chillers with cooling capacities higher than 26 kW,

the cooling capacity is divided among two cooling cycles.

The second cycle cannot be regulated using the

CH-DIN regulation because there are not enough inputs

and outputs and requires an additional C2-DIN regulation.

The C2-DIN regulation controls the same functions

together with the CH-DIN regulation. These functions

are only displayed by LEDs. An alarm from the second

cycle is displayed on the CH-DIN regulation display as a

code, e.g. “E 01”.

The CH-DIN regulation is still used to program the settings

of the second cycle.
