Principles of operation

Logamatic EMS RC35 programming unit - Subject to technical modifications

Saving data

If the power supply is interrupted, the RC35 programming unit saves the solar gain data for as long

as the time buffer lasts. If the interruption lasts longer, the recordings are reset to zero and start

again. The same applies if the date in the RC35 is changed. If the time is changed, the graphic

display is set to zero and the data recorded in the table for the week is retained. During

commissioning, the recording of data only starts once the date and time have been set.

4.11 Shutting down/switching off

The RC35 programming unit is powered via the heating system and remains permanently ON. The

heating system is only switched off, for example, for maintenance work.

B To switch the heating system on and off: set the ON/OFF switch on the boiler programming unit

to position 1 (ON) or 0 (OFF).

After shutting down or in the event of a power failure, the date and time are retained for

up to 8 hours. All other settings are retained permanently.
