Mount Wallplate or Subbase
IMPORTANT
Use a spirit level to accurately level the wallplate or
subbase as shown in Fig. 1. Inaccurate leveling may
cause the thermostat to deviate from setpoint.
When using the T87F with a Q539 Subbase, follow
the mounting and wiring instructions for the subbase.
Use the cover ring (if desired), adapter plate (if needed),
wallplate or subbase, T87F and screws as shown in Fig. 2 and
3.
IMPORTANT
Before mounting the thermostat, see Setting and
Checkout section, Heat Anticipator Adjustment sub-
section.
1. Place the cover ring on the wall at the desired location
with the cable entrance holes to the left.
NOTE: If an outlet box is used, place the cable entrance
holes toward the bottom. The side showing MADE IN
U.S.A. must be against the wall.
2. Pull the thermostat cable through the entrance hole of
the cover ring and the entrance hole of the wallplate or
subbase and adapter plate (if used).
3. Fasten the cover ring, adapter plate (if used), and the
wallplate or subbase.
4. Level the wallplate as shown in Fig. 1 and tighten the
screws.
5. After wiring the subbase or wallplate, plug the hole to
prevent interior wall drafts from affecting the thermostat.
6. Align the thermostat over the wallplate and tighten the
three captive mounting screws.
