INSTALLATION

!WARNING

Thermostat installation and all components of the control system shall conform to Class II circuits per the NEC code.

Remove Old Thermostat

A standard heat/cool thermostat consists of three basic parts:

1.The cover, which may be either a snap-on or hinge type..

2.The base, which is removed by loosening all captive screws..

3.The switching subbase, which is removed by unscrewing the mounting screws that hold it on the wall or adapter

plate. Before. removing wires from old thermostat, label each wire with the terminal designation from which it was attached. Disconnect the wires from the old thermostat one at a time.. Do not let wires fall back into the wall.

Installing New Thermostat

1.Pull the thermostat body off the thermostat base.. Forcing or prying on the thermostat will cause damage to the unit..

2.Place base over hole in wall and mark mounting hole locations on wall using base as a template..

3.Move base out of the way.. Drill mounting holes.. If you are using existing mounting holes and the holes drilled are too large and do not allow you to tighten base snugly, use plastic screw anchors to secure the base..

4.Fasten base snugly to wall using mounting holes shown in Figure 1 and two mounting screws.. Leveling is for appearance only and will not affect thermostat operation..

5.Connect wires to terminal block on base using appropriate wiring schematic (see diagrams on next page)..

6.Push excess wire into wall and plug hole with a fire resis- tant material (such as fiberglass insulation) to prevent drafts from affecting thermostat operation..

7.Carefully line the thermostat up with the base and snap into place..

Battery Location

2 "AA" alkaline batteries are included in the thermostat at the factory with a battery tag to prevent power drainage.. Remove the battery tag to engage the batteries..

To replace batteries, set system to OFF, remove thermostat from wall and install the batteries in the rear along the top of the thermostat (see Figure 1)..
