CB2 (Control Box) converts thermostat heating and cooling demand signals into controls for water valves and air valves.

There are two Plug & Play ports, labeled “THERMOSTAT” (input) and “AIR VALVE” (output). The “THERMOSTAT” port consists of two 0-10V signals from the thermostat representing heating demand and cooling demand. The “AIR VALVE” port will control MIT air valves attached to the trough. An internal terminal block provides water valve control connection points.

The CB2 draws 24VAC power from an MIT air valve chain through the “AIR VALVE” output port.

One (1) PAP-1J Plug & Play Cable is included.
