4. Function Description

4.1 Temperature Setting - TCH, TS, TD
Cooling mode (TCH = C)
When T (temperature-present value) is higher than TS + TD
PV
(temperature-set value + temperature di erential),
work1 will be turned on, and cooling will begin;
When T (temperature-present
PV
value) is lower than TS (temperature
-set value),
will be turned o , and cooling will
stop.
For example: TS = 15°C, TD = 5°C, as
shown in Fig. 8.
Heating mode (TCH = H)
When T (temperature-present value) is lower than TS - TD (tempera-
PV
ture-set value - temperature di erential),
turned on, and heating will begin;
When T (temperature - present
PV
value) is higher than TS (temperature
-set value),
will be turned o , and heating will
stop.
For example: TS = 15°C, TD = 5°C, as
shown in Fig. 9.
4.2 Temperature Protection Time - TPT
WORK1 is a temperature socket and the time interval from its power-o
to power-on again should meet the time requirement for TPT. If not,
will flash.
This protection time requirement should also be satisfied when the
controller is just powered on.
