Chilled water air conditioning system
Installation and operating instructions
6.6 Electro-mechanical model with EC fan
The required room temperature and fan stage and, if
necessary, heating or cooling mode are set on the climate
controller. The fan runs from a certain difference between
the set room temperature and the actual value and the
thermoelectric actuator opens the water-side valve.
If a condensation alarm is fitted, the PCB fitted in the cassette
for the condensation pump closes the cooling valve and opens
the max. 24 V AC/2 A potential-free alarm contact.
The climate controller type 30155 and type 30256 enables the
operation and temperature control of a max. of 2 parallel
wired KaCool D AF (230 V electromechanical version with EC
fan).
Set the room temperature on the climate controller type 30155
using the dial and fan stage in manual mode via a 3-stage slider
switch or continuously variably in automatic mode.
The room temperature is set on the climate controller with
clock type 30256 using sensor-controlled function keys.
With manual 10-stage fan speed adjustment, automatic
summer/winter changeover and a day or week program.
A separate room temperature sensor type 148921, a potential-
free contact can be connected to both climate controllers for
switchover to ECO mode or On/Off and, with 2-pipe systems,
a clip-on sensor type 148922 can be connected in conjunction
with a 3-way valve or a potential-free contact for heating/
cooling switchover, although there are only 2 inputs available
on the climate controller type 30256 which can be used
depending on the configuration.
