System Controller; Checklist For Gas And Electricity - Rinnai CHS199100 Installation And Operation Manual

SYSTEM CONTROLLER

The system controller maintains communication
between the tank and tankless to effectively control
the tank temperature based on the selected
temperature on the tankless unit.
By reading the tank temperature (J22) and tankless
outlet temperature (J2), the System Controller will
energize (120V) the pump when the tank
temperature drops. When the tank temperature
returns to the selected set temperature the System
Controller will de-energize the pump and remain in
standby until the tank temperature drops again.
ATTENTION
When power is supplied, the System Controller will
maintain pump operation. If system is not in use for
an extended period of time, Disconnect power from
the system.
