16. CONNECTING THE CLIMATE ADJUSTER: ECO CRONO (accessory available on request)
Attention: only make adjustments to the electronic board after disconnecting the power supply (see §10: access
to live components)
The following adjustment can be made on the electronic board
:
TR = Heating temperature adjustment potentiometer (CH1)
Adjusts the heating delivery temperature according to the set climate curve.
TR temperature range: 25 ÷ 80°C
(see climate curve selection table)
With the external probe, this device acts as a maximum temperature limiting device.
For dual-zone models
(RA2Z),
heating temperature adjustment only applies to the mixed zone. The other zone works
directly with the temperature of the inlet water from the centralised system.
