Installer Manual 12
6 System Type – Selects the system type for your installation. NOTE: Changes made to this option will
reset options 7 through 15 back to their default values dependent on the system type.
7 1st Stage Differential – Selects a 1st stage temperature differential.
8 2nd Stage Differential [note 2] – Selects a 2nd stage temperature differential.
9 1st Stage Fan Control [note 3] – Selects a 1st stage fan control of either gas or electric heat.
10 Emergency Heat Fan Control [note 2] – Selects emergency heat fan control of either gas or electric heat.
11 Reversing Valve [note 4] – Selects the output state of the O/B terminal. Select O for this terminal to
be active in the cool mode or select B for this terminal to be active in the heat mode.
12
Auxiliary Fossil Fuel Heat Pump Control [note 2] – When set to electric (AE AUX), both the compressor
(1st stage) and auxiliary stage(s) will run when a call for auxiliary heat is made. When set to gas (AG AUX),
the compressor stage(s) will be locked out one minute after a call for auxiliary heat. NOTE: This option can
be overridden if setting an auxiliary heat balance point in Option 28.
13
Compressor Power Outage Protection [notes 2, 5] – Selects power outage protection on or off. When
enabled, this thermostat will provide cold weather compressor protection by locking out the compressor
stage(s) of heating for a period of time after a power outage greater than 60 minutes.
14 AC Power Interrupt Warning [note 5] – When enabled, the thermostat will display an outage warning
when AC power to the thermostat is lost.
15 Short Cycle Protection [note 6] – Selects the number of minutes the cooling compressor will be
locked out after turning off. This short cycle protection is also active in the heat mode if a heat pump
system was selected in Option 6.
16 Residual Cooling Fan Delay [note 6] –
Selects a delay for the system fan after the cooling compressor
has turned off. This delay will help remove the remaining cool air out of the ductwork providing
additional efficiency.
17
Circulating Fan Lock – When enabled, the only user fan options available are ON and CIRC (Circulation).
The AUTO option is not available with this option enabled.
18
Adaptive Recovery Mode (early recovery) [note 7] – Enables or disables the ARM
TM
(adaptive recovery
mode) feature. During ARM, room temperature is recovered by turning on the heating or cooling before the
end of the set back period. The set point temperature is changed to that of the upcoming program temperature.
19 Indoor Remote Sensor Control [note 8] – If a Braeburn
®
indoor remote sensor is connected during
installation, the thermostat will automatically detect the sensor. When an indoor sensor is detected, you
may select between thermostat only (I SENS), remote sensor only (E SENS) or combining the thermostat
and the remote sensor (A SENS). NOTE: This option does not apply to a Braeburn outdoor sensor. When
an outdoor sensor is connected the thermostat automatically recognizes it and no further configuration
is necessary.
20 Lockout Security Level – Selects the level of keypad lockout when the thermostat is locked. Level
2 locks the entire thermostat (including the front reset button). Level 1 locks everything except the
SpeedBar
®
allowing for up and down temperature adjustment. NOTE: The lock code is set in the
User Settings mode (see User Manual).
