MOUNTING WALLPLATE ON OUTLET BOX
Use cover plate, wallplate assembly, T87F, and screws
as shown in Fig. 3.
1. Place the cover plate on the outlet box with the cable
entrance holes toward the bottom.
2. Pull the thermostat cable through the bottom hole.
3. Align the diamonds on the cover ring vertically and
secure cover plate with the screws provided.
NOTE: The side reading “Made in U.S.A.” must be against
the wall.
4. Position the wallplate assembly and pull the thermo-
stat cable through the cable entrance hole.
5. Mount wallplate with the two screws provided.
Tighten screws after the wallplate has been leveled. See
Fig. 1 for leveling instructions.
WIRING
All wiring must comply with local electrical codes and
ordinances. Disconnect power supply before connecting
wiring to prevent electrical shock or equipment damage.
The T87F is adaptable to most 2-wire, 24 to 30 volt
heating systems, and to most 3-wire, 24 to 30 volt
heating systems controlled by a Series 10 Thermostat.
The following hookups are typical applications. See Figs.
4-8. When using the T87F for cooling control, refer to
the hookups in the Q539 Subbase instructions.
For variations of these systems, refer to the installation
instructions for the controlled equipment.
After wiring the wallplate, plug the hole to prevent
drafts that may affect the thermostat.
