23. Only units using the main hydronic coil for both heating and cooling 2 pipe changeover and 4 pipe changeover units use the entering water temperature sampling function Two pipe changeover and 4 pipe changeover applications allow the main coil to be used for heating and for cooling therefore these applications require an entering water temperature sensor When three way valves are ordered with a Tracer ZN520 control the controller is factory configured to disable the entering water temperature sampling function and the entering water sensor is mounted in the proper location Disabling entering water temperature sampling eliminates unnecessary water flow through the main coil when three way valves are used The controller invokes entering water temperature sampling only when the measured entering water temperature is too cool to heat or too warm to cool Entering water is cold enough to cool when it is five degrees below the measured space temperature Entering water is warm enough to heat when it is five degrees above the measured space temperature When the controller invokes the entering water temperature sampling function the unit opens the main hydronic valve for no more than three minutes before considering the measured entering water temperature An initial stabilization period is allowed to flush the coil This period is equal to 30 seconds plus half of the valve stroke UNT SVX07D EN time Once this temperature stabiliz

The controller continuously operates the fan when in the occupied occupied standby or occupied bypass mode When the controller is in the unoccupied mode the fan is cycled between high speed and OFF with capacity Even if the controller is configured for continuous fan operation the fan normally cycles with capacity during unoccupied mode While unoccupied the fan cycles ON or OFF with heating cooling to provide varying amounts of heating or cooling to the space If alocal fan mode switch determines the fan operation the OFF position controls the fan to off The user can communicate a desired operating mode such as OFF heat and cool to the controller If OFF is communicated to the controller the unit controls the fan to off There is no heating or cooling Table 56 Valves remain closed UC400 Probable Cause Unit wiring Failed end device No power to the controller Diagnostic present 124 Explanation The wiring between the controller outputs and the valve s must be present and correct for normal valve operation Refer to applicable wiring diagram The valves must be checked to ensure proper operation If the controller does not have power the unit valve s will not operate For the controller to operate normally apply an input voltage of 24 Vac If the Marquee Power LED is OFF continuously the controller does not have sufficient power or has failed Several diagnostics affect valve operation
