Two-pipe, one- or two-temperature, pneumatic thermostat used to
provide proportional control of pneumatic valves and damper
actuators in heating and air conditioning systems. Replacement
kits are available for Johnson, Powers, Robertshaw, Barber-
Colman, and older Honeywell two-pipe pneumatic thermostats.
• Durable TP970 Series Thermostat. Pilot operated for high capacity.
• Two-temperature energy conservation model available.
• Adapter plate in Convertastat kits covers existing thermostat
wallmark.
• Backplate has molded air connections-no separate fittings needed.
• Universal locking cover with satin chrome finish and horizontal,
vertical, or blank window options with Tradeline model-other covers
available.
