Power source should be the same as ECON-ZIP-BASE.
50
When the thermostat is not equipped with occupancy control, "Fan On" output "G" shall be wired to the ECON-ZIP-BASE.
Existing refrigeration safety devices may exist, consult RTU wiring diagram
51
53
If RTU is not a Heat Pump using a conventional thermostat and it is desired to record heating operation hours, connect W1 to ECON-ZIP-BASE.
56
W1 must be wired for Heat Pump operation if conventional thermostat is used in conjunction with Defrost Board.
If Thermostat and RTU use O/B control reversing valve position, O/B must be wired to W1 on ECON-ZIP-BASE.
52
Actuators can be mounted in parallel with the ACT3 output from the ZIP Economizer. The ACT5 feedback input should be wired to the Outside Air damper actuator feedback wire.
57
Thermostat with two (2) stages of cooling required. Thermostats with mercury switches are not compatible with the ZIP Economizer.
58
Iso relay may be required with certain RTU manufacturers.
