A pressure differential switch is used to prevent a heater from operating if there is no airflow across the heating elements. The switch is provided with a pitot tube to be installed into the duct, which makes it sensitive to velocity pressure as well as to static pressure. In applications where there is not enough pressure to activate a differential pressure switch, an electronic air flow sensor should be specified.
Electronic Sequencer The TH34 electronic sequencer has been designed as a compact solution to replace bimetallic mechanical sequencers to split loads into smaller delayed sequences. When the thermostat contact closes, Q1 is instantly activated and then Q2 to Q4 after approximate...

Duct sensor The DS-600 is a thermistor based duct sensor designed to work with Thermolec’s thermostats and electronic controllers to modulate the heater’s capacity according to the heat required. In most cases the DS-600 is used with Thermolec’s 0-10 VDC Room Thermostat to allow...

Pilot lights are mounted on the control box to indicate that either a function of the heater is operating or a failure condition is present. The most commonly specified pilot lights functions are: power on, heating on, no airflow, overheating, stages on. The pilot lights' functio...
