4. Activate the buffer tank function by selecting the number of sensors:
Parameter
(BP001)
5. Select the operating mode for the buffer tank.
Adjustment required
By default, the buffer tank is managed as a low-loss header and does not require any spe­
cific settings. The temperature set point for the buffer tank is equal to the maximum set
point temperature value taken from all the associated circuits.
Example: with the temperature set points of CIRCA1: 22 °C, CIRCB1: 21 °C and CIRCC1:
20.5 °C, the buffer tank set point will be: (Maximum temperature for CIRCA1, CIRCB1,
CIRCC1) = 22 °C.

The buffer tank is used to store energy either via the buffer tank timer
programme or by a contact connected to the TEL digital input. The buffer
tank must be installed and configured with one or two temperature
sensors.
1. Program the load timers for the buffer tank.
