RAB... Series Electronic Room

Thermostats

Designed for good control and minimal

complexity, the RAB... Electronic Room

Thermostats deliver fan coil control at a very

economical price. Ideal for schools, public

buildings, storage or maintenance rooms

requiring on/off control output, the RAB10.1U

is the basic electronic thermostat that delivers

2-pipe fan coil control. Designed for use in

conjunction with zone valves, thermal valves

and fans, the RAB20.1U provides 2-pipe fan

coil control with an external setpoint knob

and an external changeover switch for easy

adjustment by users. Also designed for use in

conjunction with zone and thermal valves in

4-pipe fan coil systems, the RAB30.1U offers

two outputs to control separate heating and

cooling zone valves, a manual setpoint knob,

manual changeover and fan speed control.

The RAB90.1U provides remote control of

a 3-speed fan.

RCC... Series Electronic Fan Coil

Unit Controllers

Featuring integral microprocessor-based

technology for extreme accuracy, the RCC...

Electronic Fan Coil Unit (FCU) Controllers

are a step above their peers—offering the ease

of operation and the added flexibility of auto-

matic heat/cool changeover with three

operating modes: normal, energy saving and

freeze protection. Other highly desirable

features, such as LEDs for easy, at-a-glance

monitoring of mode and fan speed, are also

included. Designed for 2-pipe fan coil units,

the RCC10U provides one output with auto-

matic heat/cool changeover, remote air

temperature sensor inputs and operation

mode changeover inputs. The RCC20U FCU

Controller is designed for 2-pipe fan coil units

Fan Control

Applications

with an additional electric heat output and has

the same features as the RCC10U. For 4-pipe

fan coil units with Free Energy Band™ for auto-

matic changeover, the RCC30U FCU Controller

provides two on/off outputs and a return air

sensor for additional control response and

accuracy to maintain comfort. Designed

with two control sequences with Free Energy

Band™, the RCC30U allows the room temp-

erature to float several degrees around the

setpoint without switching into heating and

cooling mode for optimal energy efficiency.

RDF... Series Modulating Electronic

Fan Coil Unit Controllers

Offering the advantages of digital technology

and precise microprocessor-based control, the

RDF... Modulating Electronic Fan Coil Unit

Controllers deliver superior control of two- and

four-pipe fan coil applications as well as the

features users want most. The RDF... Series

delivers the ease of operation together with

the most flexibility, featuring operation mode

changeover, heat/cool changeover and return

air temperature input. Excellent for 2-pipe

fan coil heating or cooling applications, the

RDF10U provides one on/off input for valve

control and outputs for a 3-speed fan.

The RDF20U adds an additional output for

applications with electric heat. For 4-pipe

heating and cooling, the RDF30U features two

on/off outputs. Ideal for office, hotel and other

high profile installations where comfort and

asset protection is a must, the RDF50.1U

provides 0 to 10 Vdc output while the

RDF60.1U provides 3-point floating 24 Vac

output. Both models deliver Proportional (P) or

Proportional + Integral (P+I) control. All models

feature an easy-to-read LCD and the capability

for automatic heat/cool changeover as well as

display of either setpoint or room temperature.
