White Rodgers 1F83-261 Installation and Operation Instructions

Brand: White Rodgers

Model: 1F83-261

Category: Thermostats

Type: Installation and Operation Instructions

White Rodgers 1F83-261 is a non-programmable electronic digital multi-stage thermostat, designed to provide precise time/temperature control for your home. It's compatible with heat/cool systems with up to two stages of heating and two stages of cooling. It also features a large, easy-to-read LCD display that continuously shows the current temperature and setpoint, as well as a backlit display that activates when any key is pressed.

WARNING

Do not use on circuits exceeding speciﬁed voltage.

Higher voltage will damage control and could cause

shock or ﬁre hazard.

Do not short out terminals on gas valve or primary

control to test. Short or incorrect wiring will damage

thermostat and could cause personal injury and/or

property damage.

Thermostat installation and all components of the

system shall conform to Class II circuits per the NEC

code.
