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.
