Braeburn 5220 Installer Guide - Manual (Page 13)

13 Installer Guide
15 AC Power Interrupt Warning [note 6] – When enabled, the thermostat will display an outage warning
when AC power to the thermostat is lost.
16 Short Cycle Protection [note 7] – 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.
17 Residual Cooling Fan Delay [note 7] – 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.
18 Adaptive Recovery Mode (early recovery) [note 8] – 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 9] – 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).
21 Auto Changeover Dead Band [note 10] – When auto changeover mode is enabled in option 5 and
selected, the system automatically switches between heating and cooling when the room temperature
meets the normal criteria for either a heating or cooling call. There is a forced separation (dead band)
between the heating and cooling set points so that the systems do not work against each other. This
option selects the amount of this dead band in degrees with the default being 3° F.
22 Compressor Balance Point [notes 4, 11] – Locks out the use of the compressor heat stage when the
outside air temperature is less than the selected setting of 15° F to 50° F (-9° C to 10° C)
23 Auxiliary Heat Balance Point [notes 4, 11] – Locks out the use of the auxiliary heat stage when the
outside air temperature exceeds the selected setting of 70° F to 40° F (21° C to 4° C). NOTE: This balance
point overrides the fossil fuel compressor lockout in option 13. If this option is set to gas and the outdoor
temperature is over the auxiliary balance point, the compressor will remain on during a call for auxiliary heat.
24 Heat Set Point Upper Limit – Selects the heating set point upper adjustment limit.
25 Cool Set Point Lower Limit [note 7] – Selects the cooling set point lower adjustment limit.
