Wiring the CDP Proportional Controller
The CDP controller is designed to accept
various modulating input signals: 0-10
Vdc, 0-20 Vdc, 2-10 Vdc, 0-20 mAdc and
4-20 mAdc. The DIP switches located on
the back of the controller must be set for
the appropriate input signal.
NOTE: the modulating signal must come
from a controller or DDC system, not a
sensor. The CDP controller follows the
input signal being off at low signal and full
on at full signal.
Wiring the CDH Humidity Readout
Proportional Controller
The CDH controller is designed to accept
an input signal from a humidity sensor
(not controller). This input signal is then
displayed on the controller as the relative
humidity. Set point and differential are
entered into the CDH controller making it
stand-alone.
Wiring the CDD Humidity Readout
Proportional Controller/Dehumidify
The CDD controller is designed to accept
an input signal from a humidity sensor
(not controller). This input signal is then
displayed on the controller as the relative
humidity. Set point and differential are
entered into the CDD controller making it
stand-alone.
The connections 66-67 are only for
connection to the Macrobase controller for
humidification/dehumidification
management of air handling units. Max:
5ma, 30vdc. There is also a dehumidify
contact that can be connected to a
dehumidifier. The dehumidify contact is
limited to 24 Vac/dc at 1 Amp.
There is also a CDT controller that reads
a temperature sensor input and controls the SD humidifier for use in a Turkish bath. It is wired the same was as the
CDH controller, but with a temperature sensor instead.
