UCM 4.2 Retrofit Kit

The UCM 4.2 retrofit kit is available in three basic kits.

•Retrofit Kit with a Honeywell actuator

•Retrofit Kit with a Belimo actuator

•Retrofit Kit with no actuator

The kit may also be ordered in a pres- sure dependent version on a special basis. Both the Belimo and Honeywell actuators are direct coupled actuators.

Honeywell Actuator

Key benefits and features of the Hon- eywell actuator are:

•Selectable 45°, 60°, and 90° angles of rotation

•35-inch-pound torque capacity

•3/8-inch to 1/2-inch shaft size capa- bility

•90-second drive time over 90° rota- tion

•Magnetic coupled motor provides 45-inch-pounds stall

•2 VA at 24-volts power consumption

•Manual clutch to disengage the ac- tuator from the motor

Belimo Actuator

The Belimo actuator’s principle benefit is flexibility. Belimo is designed with the following features:

•Direct coupled with universal clamp fitting shaft sizes, 3/8-inch to 1/2- inch shaft size.

•Manual clutch to disengage the ac- tuator from the motor

•Motor reversing switch to change rotation

•Adjustable mechanical stops

•35-inch-pounds torque capacity

•3 VA at 24-volts power consumption

•95-second run time

Control Assembly

The actual control assembly consists of UCM and Delta P transducer mount- ed in a sheet metal enclosure. The ac- cessories offered with the kit are zone sensors with the same options as Trane DDC/VAV: flow bars for use with units without a flow sensor and con- trol power transformers.
