The Room Unit controls the heating and the domestic hot
water tank. This unit combines the functions of remote
control of the boiler and of the heating circuits and the room
thermometer. The Room Unit displays all the information
on the status of the system, so that you can choose from
various heating functions. The unit enables up to 3 weekly
schedule programs both for heating and for domestic hot
water.
In this configuration, the boiler continuously adapts its
operation to the outside temperature while taking the indoor
temperature into account.
