PRECAUTIONS  

This control is a precision instrument, and should be handled  

carefully.Rough handling or distorting components could cause  

the control to malfunction. Take care not to push or damage  

the internal bimetal sensing element during installation.  

WARNING  

!

Do not use on circuits exceeding specified voltages.  

Higher voltages will damage control and could cause  

shock or fire hazard.  

Do not use on inductive loads. Inductive (motor) loads  

will damage control and could cause shock,fire hazard  

or failure of thermostat.  

CAUTION  

!

To prevent electrical shock and/or equipment damage,  

disconnect electric power to system, at main fuse or  

circuit breaker box, until installation is complete.  

All wiring must conform to local and national electrical codes  

and ordinances.

Summary of Contents

• Page 1: Electric heat thermostat installation instructions. Failure to read and follow all instructions carefully before installing or operating this control could cause personal injury and/or property damage. The B50 Electric Heat Thermostat is designed for use on all types of electrical heating installations such as cable heat, baseboards, wall insert heaters, etc. The B50 thermostat is intended for use on 240 or 277 VAC where local codes require that a double line disconnect thermostat be used. This thermostat can also be used on 120 VAC. The thermostat may be set anywhere between 40° and 80°F by turning the knob to the desired setting. Turning the knob to the “OFF” position will break both sides of the line. This control is a precision instrument and should be handled carefully. Do not use on circuits exceeding specified voltages. To prevent electrical shock and/or equipment damage, disconnect electric power to the system until installation is complete. All wiring must conform to local and national electrical codes and ordinances.
• Page 2: INSTALLATION The control should be mounted in the wall, approximately five feet from the floor, as near as possible to the center of the controlled area. It should be mounted on a partitioning wall, not on an outside wall. WIRING All wiring must conform to local and national electrical codes and ordinances. The thermostat may be mounted in any standard 2 x 3 electrical outlet box. Disconnect electrical power to the system at main fuse or circuit box. Make electrical connection to thermostat leads with wire nuts or other local code approved devices. Take care not to push or damage the bimetal sensing element during installation. Temperature Limiting Option is for applications where the temperature setting of the control is to be set and protected from unauthorized adjustment. Remove cover from thermostat to limit the temperature range. Check that knob rotation is limited in travel as set by the pins.
