Product Description
Honeywell TS244A Wall Mount Temperature Sensor (40° to 80°F)
Selectra® Series 44 systems are designed primarily for space heating, as components of direct fired equipment. A wall mounted Selectrastat® senses space temperature and has an integral selector with either a 55° to 90° F or 40° to 80° F range. A discharge air temperature sensor (and mixing tube) is a means of limiting the minimum and maximum discharge air temperature.
The systems utilize Modulator or Modulator-Regulator valves to control gas pressure. Amplifiers are available with adjustable low-fire start duration.
