Product description
The differential temperature controller with 3-digit LED seven segment display, 6 keys and 4 relays
is variably applicable due to its freely programmable general functions. Either differential or stan-
dard regulation can be selected via parameters. With four digital inputs a logic evaluates status
messages from a connected refrigerating plant and thus guarantees a defined operational se-
quence under all conditions.
As a special feature of the power board the output relay for the compressor is switched off as soon
as the digital input for the high pressure alarm is opened.
