12 - OPERATION OF 30WG UNITS WITH SPECIFIC HEATING CONTROL (OPTION 153)
12.1 - Operating principle
Units have been designed to optimise the operation of heating installations that require hot-water production for a traditional heating
system and domestic hot-water production.
The TouchPilot Junior control system of the units includes algorithms that permit constant automatic optimisation of:
- control of a directional on/off three-way valve based on the heating or domestic hot water requirements
- control of the electric heating stages allowing relief of the heating loop
- hot-water setpoint reset (heating application) based on the air temperature
- priority control between heating application and domestic hot-water application.
NOTE: The installer is responsible for ensuring that the installation complies with the applicable legislation in terms of
electrical and thermal safety.
