2211 through 2218 Series
Room Thermostats
These pneumatic room thermostats are designed for proportional temperature control of pneumatic valves and damper actuators to maintain room air temperatures in heating, ventilating, and air conditioning systems.
Features:
•Small size, approximately 2 x 2 in. (51 x 51 mm).
•Factory calibrated. Stainless steel ball-in-seat provides pneumatic feedback for linear, stable operation.
•Easy-to-use throttling range adjustment and recalibration.
•Adjustable bimetal shows actual throttling range in both °F and °C. Adjustable 2 to 12°F (1 to 6.7°C).
•Setpoint (in both °F and °C) shown on thermostat body with cover removed.
•Leakproof, O-ring sealed, spring-loaded self-closing branch gauge tap.
•2214 and 2216:
-Separate factory-calibrated night bimetal and setpoint dial, with fixed 4 F° (2 C°) night throttling range for accurate “night” operation.
-Snap-acting (not gradual) changeover from “day” to “night” operation and vice versa.
•2216:
-Third port (R) output with manual reset lever allows full restoration of day operation (typically, of unit ventilator), with either manual or automatic reset to day-night schedule.
•2218:
-Snap-acting (not gradual) changeover from direct-action to reverse-action and vice versa.
