INPUTS/OUTPUTS

Single Duct Air Terminal Zone Controller

(33ZCVAVTRM) —

The input and output channel assign-

ments are shown in Table 2.

The zone controller provides seven analog inputs.

ANALOG INPUTS — The analog inputs consist of four ther-

mistor type inputs and two 0 to 10 VDC inputs. The thermistor

inputs conform to the nominal 10K thermistor values in

Table 1.

TRIAC OUTPUTS — The zone controller has four 24-VAC

triac outputs on the baseboard. These outputs are capable of

switching 24 VAC at 1 Amp with a power factor of 0.8. Two

triacs control the primary output damper. One drives the damp-

er clockwise and the other counterclockwise. The two other tri-

acs are dedicated to the control of either proportional or two

position heat.

The specific output requirements for the air terminal appli-

cations are given in Table 3.

*Required whenever ducted heat is to be controlled. If monitoring of supply air is required the zone controller must be configured for heat even if

the box does not contain heat. It is also required for stand-alone operation.

†Primary air sensor is required whenever unit is configured as a master zone controller and a non-CCN air source is used.

**24v connection (J4-16) is required for RH sensor only.

Table 3 — 33ZCVAVTRM Zone Controller Outputs

*These terminals provide 24 VAC-output power to the load.

†The zone controller comes wired and configured for clockwise closure of the primary air damper. Do not change wiring to change rotation. The

installer should configure the rotation decision with Carrier software to ensure transducer calibration integrity.
