HOT STANDBY
If sequencing is used, sensor 2 on the unit can be connected to a shell temperature
sensor to enable the hot standby feature. Setpoint 2 on the unit is configured to the
standby setpoint and whenever the sequenced slave disable command is sent, the
control will override this to maintain the standby water temperature.
