Thermostat Operation
Minimum Run Time (MRT)
The thermostat has a Minimum Run Time (MRT) delay after
the start of any heating or cooling call. This minimum run
time assures even heating and cooling cycles. The MRT will
keep the system on, even if it reaches the setpoint room
temperature, or you change the setpoint to a temperature
that would satisfy the call, until the MRT expires. Changing
the Mode to OFF will cancel the MRT and the system will
turn off immediately. The MRT can be adjusted in the
Advanced Settings menu of the thermostat.
Note:
When MRT is active, the heating or cooling icon will be
flashing.
Minimum off Time (MOT)
The thermostat has a Minimum off Time (MOT) delay after
any heating or cooling cycle ends. This delay prevents rapid
heating/cooling cycles and also provides “short cycle
protection” for the system compressor. This delay may be
noticeable when you change a setpoint and it does not
respond immediately due to the MOT delay timer preventing
the system from restarting. The MOT delay time can be
adjusted in the Advanced Settings menu of the thermostat
but there is a minimum of a 5 minute delay to assure
compressor protection.
Note:
When MOT is active, the thermostat Status Display shows
“WAIT”.
Z-Wave
®
Operation
x
Thermostat Battery Operation:
If the thermostat is
installed in a Z-Wave network while powered by
batteries, it will be enrolled as a Z-Wave FLiRs
(frequently listening receiver slave) type device. This is
a power saving mode that conserves the batteries by
keeping the radio asleep most of the time. However, in
this mode, the thermostat does not act as a
repeater/router in the Z-Wave network.
x
Thermostat 24VAC Operation:
If the thermostat is
installed in a Z-Wave network while powered by 24VAC,
it will be enrolled as an always-listening device and can
act as a router node in the Z-Wave network.
CAUTION!
Once installed in a Z-Wave network, if you change
how the thermostat is powered (from batteries to
24VAC or vice versa), you must remove and re-enroll
the thermostat in the Z-Wave network for it to work
correctly.
