Installation Guide
Non-programmable Heat Pump Controller
The TH146-N-DE electronic controller can be used to control a heat
pump system. The following devices can be connected to the con-
troller:
heat pump
auxiliary heating (furnace)
air recirculation fan
humidifier
dual-register meter (dual energy)
remote control device (for the unoccupied mode)
• CT280-HP-2H1C control module
• TH146 console with two wall anchors and mounting screws
• AC144-03 outdoor temperature sensor (3 m or 10 ft) with
mounting clip (see section 2.7)
• RC845 relay (see section 2.5)
• AC146-410 plenum temperature sensor (see section 2.8)
• CT241 telephone controller (see section 2.10)
Install the control module on the furnace’s electrical panel, away
from the heat source.
Install the console in the area where you wish to measure the tem-
perature and humidity. Avoid locations where there are air drafts
(e.g., top of staircase or air outlet) or stagnant air (behind a door).
Do not install the console on a wall hiding air ducts nor expose it to
direct sunlight.
NOTE
: If this controller replaces an existing thermostat, the wires
that were connected to the thermostat can be used to connect the
console. The maximum wire length is 30 m (100 feet).
1)
Choose a location about 5 ft. (1.5 m) above the floor on an
inside wall.
2)
Loosen the captive screw under the console.
3)
Detach the console from its base by pulling the bottom section.
4)
Secure the base using the wall anchors and screws.
5)
Connect the console to controller terminals TH and TH (no
polarity).
Connect the heat pump to the controller as follows:
• Controller terminals R and C to heat pump terminals R and C
(see section 2.4)
• Controller terminal Y to heat pump terminal Y
• Controller terminal O/B to heat pump terminal O
• Controller terminal WW to heat pump terminal WW
