Remote Indoor Temperature Sensor
A remote temperature sensor may be used with the programmable model, where
it is desirable to install the Thermidistat Control in a limited access location while
measuring the temperature in the living space. The remote room sensor may be
used as a stand alone or average with local sensor.
Two−Piece Thermidistat Control Configuration
The Performance Series Thermidistat Control can be installed in one of two
configurations. The control may be installed as a single−piece Thermidistat
Control or it may be split into two pieces and mounted in separate locations. As
a single−piece unit, all required wiring must be brought to the Equipment
Control Module for connection to the terminal strip. In two−piece configuration,
the Display Module can be mounted in the living space while the Equipment
Control Module may be mounted near the indoor furnace or fan coil. Connection
from the Display Module to the Equipment Control Module requires only two
wires. All other control wires are connected to the Equipment Control Module
from the HVAC equipment. This configuration results in a slimmer display and
locates the Equipment Control Module containing the switching relays away
from the main living space where relay clicking will not be heard.
The model numbers on the Display Module and the Equipment Control Module
(ECM) must match or unpredictable results may occur.
Two−wire pigtail replacement part number is TX−2WR05.
Wiring
Wire length should be no more than 250 ft (76 m). Use 22 AWG or larger for
normal wiring applications. Continuous wire lengths over 100 ft (30.5 m) should
use 20 AWG or larger.
