About the CT230 linked unit
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 heat-
ing schedule on the master thermostat.
• Each CT230 linked unit is powered by line voltage (120 VAC or 240 VAC) and has its own ground fault
protection mechanism. Up to 10 CT230 linked units can be used in a given setup.
• The master thermostat (non-included) can be a TH113, TH114, TH115 or TH116 thermostat operating
on 12 VDC. The master thermostat is powered by one of the CT230 linked units.
