T8400C and T8401C

Electronic Thermostats

The T8400C and T8401C Thermostats provide single-

stage, non-programmable temperature control for 24V

heating-cooling systems with manual changeover from

heat to cool. Heating cycle rate is selectable at 1, 3, 4, 5,

6, or 9 cph. Cooling cycle rate is fixed at 3 cph.

Temperature indication can be set for °F or °C.

The T8400C Thermostat is powered through the heating/

cooling system controls. The T8401C Thermostat is

powered directly from the system transformer. Batteries

are not required because setpoints are held permanently

by non-volatile memory for all models.

All TRADELINE® models include a thermostat, wallplate

(for wiring and mounting thermostat) and owner’s guide.

The T8400C SUPER TRADELINE® model also includes

two decorator cover plates for covering wallmarks.

MERCURY 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 an old control containing

mercury in a sealed tube.
