Barber-Colman TP-8121-701 Dual Room Controller is a solid-state, dual-room control that regulates heating and cooling for two zones using a single setpoint. It offers dual output signals to drive compatible relays or actuators over a 55–85°F range and arrives in beige. The unit is listed as discontinued by the manufacturer as of May 31, 2011. In legacy HVAC installations, this dual-room controller provides coordinated two-zone temperature management when a single setpoint is acceptable for both rooms.
