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.

12.2 - Auxiliary electronic board (AUX1) - analogue and digital inputs and outputs

- Connector J2: Digital outputs CH 1 to 4 for electricals heaters 1 to 4.
- Connector J3: Digital output CH 6 to control a directional on/off three-way valve
- Connector J6: Analogue input CH 11 for outside air temperature sensors
- Connector J6: Analogue input CH 12 for information on domestic hot water demand
- Connector J7: Analogue input CH 13 for information on domestic hot water demand
- Connector J8: Analogue input CH 14 for information on summer operation only (domestic hot water only)
To apply the different configurations required, refer to the instructions in the TouchPilot Junior Control IOM.
