TH110 Thermostat with contact sensor for temperature maintenance

Maintaining Domestic Hot Water Temperature

Today, it is essential to ensure the instantaneous supply of domestic hot water to every tap in the system at the lowest possible cost. The AUTOCÂBLE cable, which eliminates the traditional “hot water loop,” keeps domestic hot water circulating continuously through the pipes.

• The investment is reduced (no more pump, heater, or return line)
• The system is highly efficient and reliable
• Consumption is optimized
• Maintenance is virtually nonexistent
• Installation requirements are reduced compared to installing a dual-loop system

Electrical connections

• First, the installation must be protected at the source by a 30 mA ground-fault circuit interrupter (GFCI) combined with a Type C circuit breaker for the pipe tracing. The amperage of this circuit breaker must be selected based on the length of the network cable.
• The installation must be carried out in accordance with current electrical regulations.

Power supply cable for the heating cord:

The maximum length will depend on the circuit breaker’s maximum amperage:

Beyond the maximum lengths and amperage supported by the thermostat, given its maximum breaking capacity, it is necessary to use a power relay. This allows a single thermostat to be used for longer cable lengths.
