Installing a buffer tank

A buffer tank is used to separate the heating circuits or to store energy.
The buffer tank is used with one or two temperature sensors. The CIRCA0
circuit cannot be used at the same time as a buffer tank.
1. Connect the temperature sensor(s) for the buffer tank to the
corresponding connectors:
Description
Buffer tank temperature sensor to the Tsyst1 connector on the
SCB-10 PCB
Buffer tank bottom temperature sensor to the Tsyst1 con­
nector on the SCB-10 PCB
Buffer tank top temperature sensor to the Tsyst2 connector
on the SCB-10 PCB
2. Configure the pump for the CIRCA0 zone as a system pump:
3. Deactivate the CIRCA0 : circuit
