Fuel SaverThermostats
Application
These thermostats provide energy saving control for a 24 Vac multistage heat pump heating/cooling system as indicated in Table 1 and are powered directly from the control transformer. All models have 5-1-1 programming.
As long as AC power is continuously available to transformer, the thermostat will be compatible with most control systems.
The T8611G,R models include SYSTEM and ENRG SAV LEDs near the top front of the thermostat. The SYSTEMLEDlightswhenthethermostatissignalingforheating or air conditioning. The ENGR SAV LED lights during the LEAVE and SLEEP periods.
TheAUX.HT.,EM.HT.,andCHECKLEDSarelocated nearthebottomcenterofthesubbase.SeeTable1.TheAUX. HT. LED lights whenever the thermostat is calling for operation of the backup or auxiliary heater. Backup (auxiliary)heatismoreexpensivetooperatethantheheatpumpand typicallyisusedonlywhentheheatpumpisunabletohandle the load. The EM. HT. LED lights whenever the thermostat system switch is in the EM. HT. position. The CHECK LED lights when something needs to be checked to maintain efficient operation of the system. Consult heat pump equipment literature to determine specific meaning of this LED.
Heat and cool anticipation is fixed in all models; no adjustment is necessary. Cycle rates are adjustable for auxiliary heating stage.

Installation
WHEN INSTALLING THIS PRODUCT..
1.Read these instructions carefully. Failure to allow them could damage the product or cause a hazardous condition.
2.Check the ratings on the product to make sure the product is suitable for your application.
3.Installermustbeatrained,experiencedservicetechni-
cian.
4.Allowthermostattowarmtoroomtemperaturebefore operating.
5.After installation is complete, check out product operation as provided in these instructions.
!CAUTION
1.Disconnect power supply to prevent electrical shock or equipment damage.
2.After wiring is complete, push excess wire back into the hole, and plug hole with nonhardening caulk, putty or insulation to prevent drafts from affecting thermostat operation.

—hot or cold air from ducts. —radiant heat from sun or appliances —concealed pipes and chimneys.
—unheated (uncooled) areas behind the thermostat, such as an outside wall.
IF REPLACING AN EXISTING THERMOSTAT
Turn off power to thermostat at furnace or heat pump. A two-transformersystemmayrequireturningofftwoswitches or disconnects. Remove any existing wallplate or subbase from the wall. Label or write down each wire color with the letterornumberonthewiringterminalasthewireisremoved, to avoid miswiring later.
IF NEW INSTALLATION
Runacabletoaholeattheselectedwalllocation,andpull about 3 in. [76 mm] of wire through the opening. Color- coded,8-gaugethermostatcablewithoneconductorforeach wiring terminal is recommended. Good service practice recommends selecting cable with one or two more conductors than the immediate application requires.
MOUNTING SUBBASE
The subbase does not require leveling for proper operation, but for appearance only.
Remove thermostat from subbase, see Fig. 1.
Thesubbasemountsdirectlyontothewallwiththescrews included in the package. Use the subbase as a template, and with a pencil, mark the two mounting screw positions, see Fig. 2. Use 3/16 in. bit to drill holes for anchors. Gently tap anchors into holes until they are flush with the wall surface.

WIRING
All wiring must comply with local electrical codes and ordinances.
Disconnect power before wiring to prevent electrical shock or equipment damage.
The shape of the terminal barrier permits insertion of straight or conventional wraparound wiring connections. Either method is acceptable.
Refer to Figs. 4-6 for typical hookups of subbase and thermostat.
NOTE: Keep all wiring restricted to ribbed area surrounding terminals to assure thermostat/subbase contact, see Fig. 3.
