thermostats can be field installed on Models HER 30 through

at 240 VAC, 18 amperes, non-inductive at 277 VAC. Pilot

duty rating is 125 VA at 250 VAC. The switch is single-pole,

single throw, open on temperature rise. Temperature range of

the dial setting is from 40°F to 90°F.

The thermostat is listed by C.S.A. as certified and is also

listed with Underwriters Laboratories, Incorporated.
