Configuring the relay stage, parameter 17
The TVS has one relay stage you can configure as one of the following options.
 Off: the relay is always open (OFF).
 On: the relay is always closed (ON). You can use this configuration as an override.
 Cool: the relay controls a cooling element and is on when the temperature is above the set point.
 Heat: the relay controls a heating element and is on when the temperature is below the set point.
 If you need to connect more cooling elements than you have relays available,
and you are not using both variable stages, you can use an available variable
stage as an ON/OFF stage (for 120/230 VAC-powered equipment only). For
