When the unit is operating from a conventional thermostat or other binary input the economizer setpoint feature relative to the cooling and heating setpoints is lost The economizer control is based strictly on a signal from the thermostat but still maintains mixed air temperature control of 53 3 F when in the economizer mode The economizer enable and disable function is still determined by the outside air sensor through the RTRM If a single stage thermostat is used only the economizer if enabled or the compressor if economizer is disabled will operate on a call for cooling A twostage thermostat is required to achieve economizer operation and compressor operation at the same time With economizer enabled a Y1 call for 1st stage cooling will be the economizer The damper will modulate between minimum position and 10096 to maintain mixed air temperature at 5373 At 50 F the damper will be at minimum position If the economizer is enabled a Y2 call for 2nd stage cooling will start the first compressor if required If the economizer is disabled 1st stage Y1 will be the first compressor If the unit has two compressors a call for 2nd stage cooling Y2 will start the second compressor When using a conventional thermostat or other binary input the ReliaTel controls will only allow two stages of cooling Figure 30 Terminal strip COM T X2 Y2 W2 G W1 0 Y1 Q O QO O O O O QO
