3.4.1.1.2.2. Separable plant water timer
This option permits to manage the “Separable plant water T timer cycles” operation mode of the separable
service for the production of domestic hot water . It allows the user to select up to 4 plant activation time
intervals, within which it is possible to define a water set point temperature.
The water T timer cycles and the relevant set point are taken in consideration ONLY if, on the RB100 or
RB200 device (absolutely necessary for the domestic hot water control) the “Type of set point inlet for the
domestic hot water” parameter is set as “digital with set point on Digital Control Panel”.
For more information please consult the installation and user booklet of the RB 100 (code D-LBR468) and
the RB 100 applications booklet (code D-LBR467), or the installation and user booklet of the RB 200 device
(code D-LBR632) and the Applications Manual (code D-LBR630), according to the type of device used.
Up to 4 daily water T timer cycles can be programmed, to which it is possible to associate 4 different
temperature levels. It is possible to enable/disable each water T timer cycle programmed without cancelling it
by operating on the
fields as described below. This programming may be different for each of the seven
days of the week.
