Note: This does not apply to MZVAV.
Temporary comfort can be provided without a zone sensor module or thermostat in place by using the outdoor air sensor or a spare supply air/return air sensor. How to do it: remove the sensor from the unit, add enough thermostat wire to it so that it can be placed in the return air stream, then connect the sensor to J6-1 & J6-2.
After the permanent zone sensor or thermostat is in place, the sensor must be removed from J6-1 & J6-2. If the RTRM does not have a space temperature input (J6-1, J6-2), or has a conventional thermostat input (G, Y, W), the unit will not run (except in the test mode).

Note: 27.5 to 50 tons - the outdoor air sensor should not be used for this purpose.
