based on a 2 to 10 VDC input from the DDC Unit Ventilator Controller
(UVC).A4to20mAinputsignalcanbeusedwiththeeldadditionof
a Belimo ZG-R01 (or equivalent) 500 ohm resistor (by others). Refer to
the wiring diagram for proper installation of the resistor. A 2 to 10 VDC
output signal is provided for damper position feedback. The gears can
be manually disengaged with a button on the actuator cover. Rotation
is counterclockwise to bypass air around coil.
The outdoor air/return air damper actuator is a unit mounted, direct
coupled, proportional control actuator that spring returns the outdoor
air damper shut upon a loss of power. The actuator provides proportional
damper control based on a 2 to 10 VDC input from the DDC Unit
Ventilator Controller (UVC). A 4 to 20 mA input signal can be used with
theeldadditionofaBelimoZG-R01(orequivalent)500ohmresistor
(by others). Refer to the wiring diagram for proper installation of the
resistor. A 2 to 10 VDC output signal is provided for damper position
feedback. Rotation is clockwise to open OA, close RA.
Face and Bypass Damper Actuator
The Face & Bypass damper actuator is a unit mounted, direct coupled,
non-spring returned actuator used for the modulation of the face and
bypass damper. The actuator provides proportional damper control

discharge air, outdoor air and room air temperature measurement. They
are located next to each other in the air stream as shown in Figure 114.
Each is wired to the terminal strip separately so that the Automatic
Temperature Control contractor may select the appropriate sensor for
the application.
10 K ohm NTC Sensor
The 10 K ohm NTC sensor is constructed from stainless steel with an
epoxy seal and twisted wire leads.
Type:
10K ohm @ 25ºC
Accuracy: ±0.2ºF, 40

±0.36ºF, 32ºF - 158ºF
1 K ohm PTC Sensor
The 1 K ohm sensor is a shrink-wrap encapsulated, PTC silicon sensing
element with stranded, tinned copper wire leads (#22 AWG).
Type:
1035 ohm @ 25ºC
Accuracy: ±0.9ºF, 5ºF - 167ºF
