PRECAUTIONS

Thisthermostatisintendedforusewithalowvoltagesystem;

donotusethisthermostatwithalinevoltagesystem.Ifindoubt

aboutwhetheryourwiringismillivolt,line,orlowvoltage,haveit

inspectedbyaqualiedheatingandairconditioningcontractor

orelectrician.

Donotexceedthespecicationratings.

Allwiringmustconformtolocalandnationalelectricalcodes

andordinances.

Thiscontrolisaprecisioninstrument,andshouldbehandled

carefully.Roughhandlingordistortingcomponentscouldcause

thecontroltomalfunction.

▲

!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.

▲

!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.
