Programmable Line Voltage Thermostat
APPLICATION
The T4600 Chronotherm® Electronic Programmable Line
Voltage Thermostat provides line voltage control of
resistance-rated heating equipment. The patented
CoolSwitch™ thyristor commutator design provides long
service life. Depending on local climate, night and day
setback of space temperature can save up to 23% of the
energy used to heat a controlled space. The precise
temperature control of the T4600 also provides 12% energy
savings during most comfort periods as compared to
electromechanical wall thermostats.
