SUPER TRADELINE
The T87F Universal Thermostat provides temperature
control for 24 to 30 Vac residential heating, cooling or
heating-cooling systems. For heating systems, the T87F
mounts on the wallplate provided. For cooling only, or
heating-cooling, use the 137421A Heating-Cooling Wall-
plate (included) with remote switching, or order the Q539
Subbase, which provides switching at the thermostat loca-
tion.
The spdt switch makes one set of contacts on a tem-
perature fall to operate the heating system. The other set of
contacts make on a temperature rise to operate the cooling
system when the T87F is used to control cooling.
Heat anticipation is adjustable, 0.1 to 1.2A.
