VCES-DDC-IOM-1C

The DDC control package is programmed for a range of

temperature control and scheduling modes which are

ﬁeld selectable. The control package enables the VHC to

control discharge air temperature, room/return air tem-

perature or discharge in conjunction with room air tem-

perature based on sensor readings. It can also be used to

control the amount of air being recirculated back into the

building.

This manual provides instructions and information on

conﬁguring and adjusting the control for a speciﬁc stand

alone or networking application.

• No extra controls needed to accommodate discharge

air temperature control.

• A room thermostat may be used to control room

heating and cooling.

• A room humidistat may be used to control room

humidity.

• Native BACnet ﬁrmware with MS/TP RS485 protocol.

• Can be optionally interfaced with many different

protocols with the use of a terminal server, like Lon-

works, Modbus, Metasys, etc.

A low voltage Field Wiring (FW) interface terminal strip

is provided for shipped loose or ﬁeld supplied controls,

sensor or interlock connections to fully integrate the unit.

Interconnections to a BMS are minimal. Refer to Appendix

G and H in the VHC-36, 42 and 50 Installation, Opera-

tion and Maintenance Instructions Manual, for example of

start-up connections, plus input and output connections

available.
