I have a Challenger 3000 series liebert with chilled water (modulating valve) and hot-water reheat (solenoid valve) for a computer room. The temperature setpoint is 75F, but the computer room is at cold at 60F (read from the liebert display). The status of the unit is the chilled water valve is at 100% open, dehumidifying. Even though the temperature is in it's alarm range (Low), the unit indicates "no alarms present". The heat is at 0%. Checked the voltage output of the main board connection that goes to the solenoid valve that controls heating water flow, no voltage. Tried raising the temperature setpoint even further, still no voltage to the heating solenoid from the board. Could this be a bad board?
