Functional Description

Display & Sensors

All temperature values can be displayed in °C or °F

with a resolution of 0,1K (0,2°F), selectable by

P21

TF201, TF 202 (PTC) as well as TF501 (Pt1000)

sensors can be used, but note that this results in

different temperature ranges. Sensor 2 (Evap. Limit

Sensor) can be disabled.

Temperature Control

The controller compares the actual room tempe-

rature

(P01)

with the control setpoint

(P03)

and

activates the cooling relay which is able to switch

solenoid valves or compressors. The switching

hysteresis (

P09

) prevents the system from short

cycling. An idle time (

P11

) prevents a compressor

from switching ON again immediately.
Setpoint range

With

P07/P08

you can limit the setpoint range to

prevent the end-user from entering critical values.

Switching mode of cooling relay K1

The switching behavior of the cooling relay

(= cooling mode) is defined by parameter

P10

2. Setpoint / day-night-shift

(1380-2 only)

To economize energy, e.g. at night, the unit can work

with a second setpoint (

P04

), which can be activated

by the internal time-switch (

P05/P06

Emergency Mode of Temperature Control

If the control sensor fails, the unit starts an emer-

gency mode.

The refrigeration relay switches on in

a percentage rate of a total period of 30 minutes,

preset by

P39

E.g.: selecting 40% means 12 minutes

on, 18 minutes off.
