CONTROL UNIT START UP PROCEDURES
When energized, Heatizon Systems Control Units turn the primary power on and off to a step-
down, low-voltage Transformer that provides power to the Heatizon Tuff Cable or ZMesh. The
Control Unit can be activated by many different types of activation devices. Examples of activa-
tion devices include simple timers and thermostats, temperature and moisture sensors and tele-
phone computer activators (see your Heatizon Systems supplier for details).
All of Heatizon System's CBX series Control Units employ "soft turn" circuits that turn the Trans-
former on without a high in-rush current from the power source. If there is a problem, the prima-
ry power to the Control Unit must shut OFF.
Warning: Make certain that any relays and circuit boards are properly seated prior to en-
ergizing the Control Unit.
