were reached. Heat setpoint range is
38º to 89ºF (3º to 32ºC).
Cool setpoint range is 59º
to 99ºF (15º to 37ºC)
or 38º to 99ºF (3º to 37ºC) if extended
cool mode enabled.
System cycles
too quickly. Anticipator setting
is too low. Reprogram anticipator setting (refer to
“Setup Mode Parameters/Functions”
which starts on page 20).
Room has high
temperature
variance. Anticipator setting
is too high. Reprogram anticipator setting (refer to
“Setup Mode Parameters/Functions”
which starts on page 20).
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 20).
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 20).
Wrong
temperature scale. Select F or C as necessary.
A Temperature
Offset has been
applied. Reset Temperature Offset (refer to
“Setup Mode Parameters/Functions”
which starts on page 20).
Wrong
temperature is
displayed.
Bad location. Ensure the thermostat is located away
from direct sunlight, drafts, doorways,
skylights and windows or exterior
walls.
Steal power
function may be
causing problems
with HVAC
system. Change power setting (Po) to “24” and
ensure you have two AA batteries
installed. Heat or cool

device does not
indicate a heat
or cool call.
Improper wiring
connections. Recheck wiring connections.

“d” (for dual setpoint operation) (refer
to “Setup Mode
Parameters/Functions” which starts
on page 20).
Bootloader
The bootloader is a low-level version of the CHV-TSTATRF’s firmware that will
become active in the event an upload of the standard firmware fails. This lets you
perform some basic functions with the goal of getting the CHV-TSTATRF back to
normal operation.
