Remote Indoor Temperature Sensor
A remote temperature sensor may be used with the programmable heat pump and
programmable air conditioner thermostats where it is desirable to install the
thermostat 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 Thermostat Configuration
The Performance Series AC/HP Control can be installed in one of two
configurations. The control may be installed as a single--piece thermostat 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 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--2WR--05.
Wiring
For all wiring applications, use 22 AWG or larger wire. Continuous wire lengths
over 100 ft. (30.5 m) should use 20 AWG or larger. Wire lengths are not to exceed
250ft.(76m)perrun.
