EXAMPLE USE # 1
Switch off the ven la on/exhaust/intake fans when
sulphur vaporizers are working.
How does it work? 24-H mer (2) is given priority and
ac vates vaporizers (6) on programmed schedule. When
vaporizers are ac vated, the mul bar (7) and OSW (3)
sense cord are powered, causing OSW OFF output (lower
plug) to shut off the exhaust fan (5) if already on. In fact,
the exhaust fan is ac ved by the Temperature Controller
(1) -example TP1 or TP2 –which supplies 120V to its out-
put. Fan control is given lower priority and will be sus-
pended when vaporizers operate. Fan opera on will only
resume when vaporizers are off.
