Wiring
IMPORTANT
1. Never use any source of power other than a self-
powered millivoltage pilot generator system.
Refer to Fig. 4. Connect a 750 millivolt system to
R and W terminals at wallplate. Connect a 250
or 500 millivolt system to R and Y terminals
at wallplate.
2. This thermostat has a fixed anticipation heater
properly sized for use with self-generating
Powerpile systems. It should not be changed.
3. Use the T87, not the TS86, in systems where the
millivoltage gas valve is controlled through a
switching relay.
All wiring must comply with local codes and ordinances for
wire size and voltage. See Fig. 4 for typical millivolt
hookup.
