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 Preferred 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
250 ft. (76 m) per run.
