RAB20.1U Thermostat with

exposed setpoint knob and

external changeover.

RAB10.1U Thermostat with 

manual changeover.

Description

Designed to control 2- or 4-pipe fan coil or unit ventilators, 
the RAB… Electric Fan Coil Thermostats are an attractive 
and economical solution that utilize two-wire, gas 
membrane technology.

Providing On/Off control, the RAB… Electric Fan Coil 
Thermostats are available with dual scale Fahrenheit/ 
Celsius models with manual or external changeover.

The RAB20.1U requires an aqua sensor to initiate 
changeover.

Features

•  Fan Speed Switch (RAB90.1U) for remote switching 

location (24...277 Vac)

•  Two-point control algorithm for on/off control
• Line 

voltage

•  2-pipe or 4-pipe fan coil applications
•  3-speed fan control
•  Fan on only models for ventilation
•  Manual or external changeover
•  Two mounting styles: electrical wall box or drywall
•  Adjustable upper/lower limit stops
•  Dual Fahrenheit/Celsius scale

Applications

The RAB… Electric Fan Coil Thermostats are 
recommended for applications in commercial or light 
industrial buildings in conjunction with zone valves, 
thermal valves, fans or thermostats.

Note:

ARG70, wall plate, is required for UL compliance in 
switching line voltage.
