The outdoor sensor provides outdoor temperature information to the transmitter which in turn sends these signals, wireless, to the microprocessor based heating systems. The heater’s brick core temperature target level adjusts automatically in relation to outdoor temperature.
A temperature sensing thermistor is connected to the two "OS" positions of the low voltage terminal strips for automatic charge control of ETS heaters. This sensor can be utilized if the transmitter is mounted in a location where it can accurately sense the outdoor temperature and will not be affected by direct sunlight or other sources of heat and cold. The temperature sensor may be affected by heat generation from inside the enclosure. However, in most applications, it provides suitable outdoor temperature sensing.
NOTE: If the transmitter is installed indoors and automatic charge control is desired, a remote outdoor sensor is required. This outdoor sensor connects to the two "OS" positions of the low voltage terminal strip in the transmitter. The existing thermistor MUST be removed before connecting a remote mounted outdoor sensor.
