CAUTION:
The CT230 linked unit is designed to be used in a system for large floor heating applications whose load is too high for a single conventional thermostat. The system consists of a master thermostat and multiple CT230 linked units (see diagram on the following page). The heating area is divided into zones of 15 A or less, each zone connected to a CT230-linked unit. The user sets the temperature and programs the heating schedule on the master thermostat.
Supplied Parts
Install each CT230 linked unit as follows:
NOTE: Connect the wires using the provided solderless connectors for copper wires:
NOTE:
WARNING: Make sure all CT230 linked units are Off.
The CT230 linked unit, with built-in ground fault protection, is different from conventional thermostats. In the event of a ground fault, the ground fault protection mechanism on the CT230 linked unit will trip and quickly stop the flow of electricity to prevent serious injury.
Definition of a ground fault
Instead of following its normal safe path, electricity passes through a person’s body to reach the ground. For example, a defective floor heating mat can cause a ground fault. Ground fault protection, does not protect against circuit overloads, short circuits, or electrical shocks. For example, you can still receive an electrical shock if you touch bare wires while standing on a non-conducting surface such as a wood floor.
Ground fault protection reset
When the ground fault protection mechanism trips, the TEST light is On (red). To reset the ground fault protection, switch the CT230 linked unit to OFF and back to ON. The TEST light will turn off if the ground fault protection is functioning properly.
End of Life
If the TEST light is flashing permanently the device must be replaced.
Testing the ground fault protection
To ensure the ground fault protection on each CT230 linked unit is always in working order, test it after installation and every month there after.
