CHV-TSTATEX Troubleshooting (Continued)
TROUBLE POSSIBLE
CAUSE(S)
CORRECTIVE ACTION
System cycles
too quickly.
Anticipator setting
is too low.
Reprogram anticipator setting (refer to
“Setup Mode Parameters/Functions”
which starts on page 19).
Poor battery
life.
Ensure that the
power switch
selection position
is proper for the
expected
conditions.
Using the 24VAC position prevents
power steal operation and causes a
device to run on battery alone if no
24 V input is available.
Using the STEAL position prevents
the 24 V input from being used even if
it is available.
Cool-only applications with nothing
connected to R or W cannot
power-steal.
Ensure heat system is available if
using power steal or follow the
cool-only notes in that section.
Check for
communication
problems using
standard RF
troubleshooting.
Fringe communication and excessive
gateway reconnect attempts cause
extended runtime which consumes
battery power more quickly.
Unit is using
remote sensors.
Avoid using remote sensors when
running on battery alone. Setup
system so that power-steal is
available.
A long backlight
time is being used.
Avoid long backlight runtimes if the
user interface is operated frequently.
Room has high
temperature
variance.
Anticipator setting
is too high.
Reprogram anticipator setting (refer to
“Setup Mode Parameters/Functions”
which starts on page 19).
Wide
temperature
variance in
single setpoint
Auto mode.
Auto Dead Band
setting is too high.
Reprogram Auto Dead Band (db)
setting (refer to “Setup Mode
Parameters/Functions” which starts
on page 19).
Heating/Cooling
not operating in
single setpoint
Auto mode.
20 minute system
toggling lockout.
Reprogram Auto Dead Band (db) and
anticipator settings for smoother
operation (refer to “Setup Mode
Parameters/Functions” which starts
on page 19).
Cannot enter
Auto mode.
Auto mode is
disabled in setup.
Reprogram Auto mode setting (AU) to
“S” (for single setpoint operation) or
“d” (for dual setpoint operation) (refer
to “Setup Mode
Parameters/Functions” which starts
on page 19).
