1. Measure the transformer voltage to check if it drops
below 23VAC while in use. The Model 5000 may not
function properly outside of the 23-28VAC range and
the transformer may need to be replaced.
2. If applying 24VAC to ‘G’ on the Sender activates ‘W1’
on the Receiver, or vice versa, then the two wires
that connect the Sender and Receiver are crossed.
Disconnect the thermostat cable and swap the
connections.
3. At the thermostat, jumper ‘R’ to ‘G’ to activate the
fan. Jumper ‘R’, ‘G’, and ‘Y’ to activate the fan and
condenser. Jumper ‘R’ to ‘W1’ to activate first stage
heat. Jumper ‘R’, ‘W1’, and ‘W2’ to activate second
stage heat. If all functions work correctly when
jumpered, then the thermostat may not be configured
properly. If no functions operate there may be a break
in the thermostat cable.
4. If the Receiver is set to the highest voltage possible
and still does not activate the equipment when called,
then the power consumption of the thermostat may
be too low. Please contact our technical support line
