Two-pipe, single setpoint, 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.
• Honeywell's best pneumatic thermostat-TP970 series.
• Shock-resistant, suspension-mounted thermostats provide
dependable performance and responsiveness year in and year out.
• Pilot operated for high capacity.
• Direct Acting (DA) and Reverse Acting (RA) models are available.
• Wide throttling range models for Zero Energy Band (ZEB) operation
are available.
• Adapter plate in Convertastat and Modernization 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.
• Typical Wide Throttling Range Application.
