Auto Changeover operation
Auto changeover is available if the thermostat is
configured for at least 1 heat stage and 1 cool stage and
ISU 3000 is set to “Auto”.
When configured this way, you can select “Auto” as one of
the options under “System mode”.
ISU 3015 is the auto changeover differential setting. It can
be set from 0-3 °F. (0-2.5 °C) to This is the minimum
number of degrees needed between the heat and the cool
setpoints when the thermostat is in auto changeover
mode. When in auto mode, the customer can always set
the heat and cool setpoint to the same temperature,
regardless of the differential setting although most
customer prefer to have a cool setpoint that is at least 3
degrees above the heat setpoint. When 0 is selected, we
enforce a 1.5°F differential behind the scenes to ensure
the heat doesn’t come on after cooling shuts off or vice-
versa.
The differential is the minimum number of degrees the
temperature needs to rise or fall before switching from
heat to cool while in auto changeover mode. Example: If
heat and cool were both set for 70, and heat had been
used last, the temperature would need to rise at least 3
degrees above the heat setpoint before the thermostat
would turn on cooling. Then it would cycle cooling on and
off to maintain setpoint and the temp would need to drop
at least 3 degrees below the cool setpoint before heat
could come on.
If the AC is used for dehumidification then we enforce an
additional temp drop below the overcooling amount, (ISU
9070) prior to switching back to heat.
Em Heat and auxiliary heat operation
Auxiliary heat:
• Auxiliary heat runs as backup to the heat pump. It runs
with the heat pump when:
• The thermostat is set to heat mode.
• The backup heat is set to electric (ISU 2180).
• Load conditions determine backup heat is needed.
The heat pump could be locked out when in heat mode by
the balance point setting (ISU 3120) or if the backup heat
is gas or oil and backup heat differential (ISU 3090) or
upstage timer (ISU 3110) are used.
Emergency heat:
Emergency heat runs when you manually switch the
thermostat to the em heat mode. When the thermostat is
in emergency heat mode, the heat pump is locked out.
Emergency heat mode is only available when the
thermostat is configured for a heat pump (ISU 2000) and
Backup heat stages is set to 1 (ISU 2071).
From home screen touch the menu icon and then “system
Mode”. You can set the thermostat to heat, off, cool,
emergency heat, or auto (auto only available if ISU 3000 is
set to auto).
When the thermostat is set to em heat mode, the heat
pump is locked out and the backup heat is used to
maintain the heat setpoint.
If ISU 2175 is set to “Drive aux and E together”, then with a
call for emergency heat or auxiliary heat, both E and AUX
terminals are energized. Typically the backup heat is wired
to Aux and E is unused when set this way.
If ISU 2175 is set to “Aux and E independent”, then with a
call for emergency heat, the E terminal is energized and
the aux terminal is not. The wire to Aux controls a heat
source that runs as backup heat to the heat pump when
the mode is set to “heat”. The wire to E controls a heat
source that runs independent of the heatpump when
mode is set to em heat. In most cases, the heat pump uses
the same heat source for auxiliary heat and em heat.
Dual fuel systems (Heat pump with gas or oil furnace
backup) cannot run the heat pump and furnace at the
same time.
Advanced Features
Adaptive Intelligent Recovery
Over time, the T10 thermostat "learns" how long it takes
your system to reach your programmed temperature
setting.
The thermostat turns on the heating/cooling system early
and assures that the programmed temperature setting is
reached at the programmed time regardless of weather
conditions. For example, if the Wake program period is set
to 6:00 am with a heat setting of 70 degrees, the heat will
turn on before 6:00 am, so the temperature is 70 degrees
at 6:00 am. The thermostat displays "In Recovery" when it
turns the system on early.
Adaptive Intelligent Recovery® calculates the recovery
ramp based on how far the room temperature is away from
the temperature setting, previous equipment performance
