T2 sensor to be placed on the water supply pipe upstream 3 way valves (not to be used with 2 way valve). The T2 sensor must
be used as described below:
•
Change-Over for the automatic switch of the operating mode. If water temperature is lower than 20°C, cooling mode is set; on the
other hand, if water temperature exceeds 30°C, heating mode is set.
•
It can be used on units with electric heater and hot water supply. The T2 priority probe activates the electric heater or water valve,
depending on the water temperature detected. If water temperature exceeds 34°C, the water valve ON-OFF control is activated; on
the other hand, if water temperature is lower than 30°C, the electric heater is activated.

A group of YHVP units with MB electronic board can be connected via a serial link and can consequently be managed at the
same time by just one JTM-B wall control or RT03 infra-red remote control. Using the special jumper present on the MB board,
one unit must be configured as the master, and all the others as slaves. The remote control must be pointed at the receiver on
the master unit. To avoid problems, it is recommended to install and connect the receiver only on the master unit.
