Installation and operating instructions
6.5 Electro-mechanical model with AC fan
The required room temperature, fan stage and, if necessary,
heating or cooling mode, are set on the room thermostats.
If the set room temperature deviates by a specific figure
from the actual value, the fan runs at the set speed 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 various room thermostats enable operation and
temperature regulation of a KaCool D AF (electro-mechanical
version 230 V with AC fan).
The room temperature is set using the dial.
3-stage fan speed setting using the slider switch.
A separate room temperature sensor type 148921and a
potential-free contact for switchover to ECO mode or On/Off
mode can be fitted onto the room thermostats type 148916
for 2- and 4-pipe systems, and a clip-on sensor type 148922 in
conjunction with 3-way valves and a potential-free contact for
heating/cooling switchover for 2-pipe systems.
