3.1.2 Installation on boiler
The unit can be installed directly on boilers equipped with EMS (Energy Management Sys-
tem).
The outside temperature sensor for outside temperature control is not delivered as stand-
ard, but can be ordered as an accessory.
3.2 Types of installation
The programming unit can be installed in three different ways:
– As the only programming unit in the system (factory setting): the programming unit is
mounted in a room in the home (the reference room) or on the boiler.
Example: detached house with one heating circuit.
– As the only programming unit in a heating system with two or more heating circuits

(Fig. 2, 1).
Examples: underfloor heating on one floor, radiators on the others; or a main flat
together with a separate annex.
– In conjunction with a remote control unit (e.g. RC20/RC20RF, Fig. 2, 2). In this case
there are always two separate heating circuits. Remote control units cannot be used
with boilers with UBA1.x.
Examples: underfloor heating on one floor, radiators on the others; or a main flat
together with a separate annex.

Both heating circuits are controlled by one programming unit.

Each heating circuit has its own programming unit / remote control unit.
