Chronotherm

III Fuel Saver Thermostats

APPLICATION

These thermostats provide energy saving control for

24 Vac conventional heating/cooling system or 750 mV

heating and 24 Vac cooling as indicated in Table 1.

Power is supplied for the device by three AA alkaline

batteries (included). This allows the thermostat to be com-

patible with all control applications.

Cycle rates are adjustable for heating.

The TS8602 current rating in heating is 0.1A at 750 mV.

The current rating on all other models is 1.6A maximum,

up to 30 Vac.

Adaptive Intelligent Recovery™/Conventional Recovery

selection screw is included on the back of the thermostat.

Fan operation switch is included on the back of some

T8602C models to select either independent or direct

thermostat control of the fan in heating.

12/24 hour clock conversion and °C/°F conversion are

available on some models only.

RECYCLING NOTICE

If this control is replacing a control that contains

mercury in a sealed tube, do

not

place your old

control in the trash. Contact your local waste

management authority for instructions regarding

recycling and the proper disposal of your old

control.

If you have any questions, call Honeywell Inc.
