CHAPTER 3: Configuring the Thermostat Using the TMI
Hold/OBO
(One Button Override) Duration
(NT130e/h and NT160e/h only)
When Button Lockout is disabled, this specifies the time interval
for the Hold function in which the thermostat temperature
settings are held independent of schedule changes due to Period
or Day Class advancements. When Button Lockout is enabled,
this specifies the time interval for One Button Override (OBO)
in which the thermostat temperature setpoints of Class #1 Day
Period are used.
Perm – The period is indefinite and the temperature setting
are either “held” or referred back to the temperature settings
noted in the Day Class Schedule for the specific Period until
the user removes this condition.
1, 2, 3, 4, 8, 12, 24 –The amount of time in hours in which
the current temperature settings are either “held” or referred
back to the temperature settings noted in the Class #1 Day
Period. The default interval is 3 hours.
Compressor Delay Specify the minimum time (in minutes) between successive
heating, cooling or heat to cool and cool to heat cycles in heat
pump applications. This parameter ensures a safe heat pump
compressor delay or off time guaranteed between cycles. This
parameter may also be used in fuel burner mode, whereby this
parameter ensures a safe A/C compressor delay or off time
guaranteed between A/C cycles.
0 – Enables the cooling system to cycle immediately upon
completion of the previous cycle. This is a diagnostic
feature and should not be left in this state or compressor
short cycling and subsequent damage may occur to the
compressor.
3 through 10 – Time in minutes required between the
completion of a cooling cycle and the next subsequent
cooling cycle. The default delay is 3 minutes.
2
nd
Stage Delay Specifies the delay between the 1
st
stage activation and 2
nd
stage
activation. This feature also controls the delay when configured
as a single stage heat pump and when the start of an Auxiliary
Heat cycle occurs.
0, 15, 30, 45, 60, 90 - Time in minutes
Fan on Heat Controls the fan state during heating cycles. In most HVAC
applications, heat activation automatically turns on the fan, but
in radiant or baseboard heat applications, the fan is activated by
the thermostat upon a call for heat if this feature is enabled.
Enabled – The fan is forced ‘on’ during heat cycles.
Disabled – The fan is not forced on during heat cycles.
