Advanced Features of the

TCM18 Ambient Control

The TCM18 has a specially designed ambient sensing control algorithm to facili-

tate the ultimate in ﬂexibility as to the number of ambient sensors and their various

location placements within a TCM18 control and monitoring module. This design

algorithm uses the following set of rules in determining the sensor and associated

control actions.
