Economizer Configuration Instructions for use with O/B
configurable thermostats with Heat pumps
When this economizer is used in conjunction with a heat
pump, special attention must be given to the thermostat.
Some newer digital thermostats only allow a single choice of
an "O" or "B" signal. When configuring this economizer for
use with one of these thermostats, the thermostat must be
configured to provide an "O" signal to ensure proper
operation of the reversing valve. Additionally the
economizers relay must be reconfigured to account for the
loss of the "B" signal. To do this, reverse the connections of
the white and yellow wires on relay terminal numbers 1 and 4.
Then reverse the green and grey wires at the relay terminal
numbers 3 and 6. Ensure that all connections are secure and
follow the regular installation instructions for all other
operations. (See diagram to the right.)
Note: Some unit wiring diagrams may still show the "B"
input signal to the unit. On these systems, connect the
applicable wires to the thermostats "O" signal.
