TEC2102-3 N2 Networked Heat Pump Thermostat Installation Instructions
12
HP stage
Sets the number of heat pump
compressor stages.
Default:
2.0
(1.0):
One Stage
(2.0):
Two Stages
Reverts the operation of a two-stage thermostat to a single-stage
thermostat when the second cooling stage is not needed.
H lock
3
Discontinues heating operation in
response to the outdoor air
temperature. Requires that an
outdoor air temperature sensor be
installed and connected.
Default:
120°F/49°C
Range:
-15°F/-26°C
to
120°F/49°C
adjustable in 5F°/5C°
increments
C lock
Discontinues cooling operation in
response to the outdoor air
temperature. Requires that an
outdoor air temperature sensor be
installed and connected.
Default:
-40°F/-40°C
Range:
-40°F/-40°C
to
95°F/35°C
adjustable in 5F°/5C° increments
Aux cont
Energizes peripheral devices
(lighting equipment, exhaust fans,
and economizers).
Default:
n.o.
(n.c.):
Contact open = Occupied; contact closed = Unoccupied.
(n.o.):
Contact closed = Occupied; contact open = Unoccupied.
The contact toggles with the internal Occupied/Unoccupied
schedule (or the NSB contact on one of the digital inputs, if used).
Hi b. p.
Sets the high balance point – the
outdoor air temperature at which the
auxiliary heat is not used.
Default:
90.0°F/32.0°C
Range:
34.0°F/1.0°C
to
90.0°F/32.0°C
Above the high balance point, only the heat pump is used to
maintain the heating setpoint. If no outdoor air sensor is connected
to Terminal OS, auxiliary heat pump operation may still be used
above the high balance point.
Lo b. p.
Sets the low balance point – the
outdoor air temperature at which the
heat pump operation terminates
when the heat pump is in the
heating mode.
Default:
-12.0°F/-24.0°C
Range:
-40.0°F/-40°C
to
30.0°F/-1.0°C
Below the low balance point, only the auxiliary heat is used to
maintain the heating setpoint. Heat pump operation may still be
used below the low balance point if no outdoor air sensor is
connected to Terminal OS.
Comf/eco
Selects how the auxiliary heat is
used.
Default:
comfort
(economy)
–
in the heating mode: If the heat pump is not able to
satisfy the heating setpoint, the auxiliary heat is energized to satisfy
the setpoint only when the temperature has dropped 2F°/1C° below
the heating setpoint.
Note:
Selecting economy in the heating mode adds a deadband
between the heat pump and auxiliary heat. The actual temperature
maintained is lower than the true heating setpoint to maximize the
heat pump operation. When the outdoor air temperature drops
below the low balance point, the deadband is eliminated.
(economy)
– in the emergency heat mode: The setpoint that is
maintained is the heating setpoint.
(comfort)
– in the heating mode: If the heat pump is not able to
satisfy the heating setpoint, the auxiliary heat is energized to satisfy
the setpoint.
Re valve
Governs the reversing valve
operation.
Default:
O
(B):
Energizes the valve in heating operation (valve is normally cool)
(O):
Energizes the valve in cooling operation (valve is normally
heat)
