8.3.5 Input release (RL)

The boiler is also equipped with an input release so that the burn-
er can be released/shutdown. This input can be used in combina-
tion with the limit switches on flue gas throttle valves, hydraulic
control valves, safety interlocks, etc. This input relates to the RL
terminals of terminal strip X6.

8.3.6 Circulation pump (Pump)

A pump with the following specifications can be connected:
- On/off pump with a mains voltage of 230 V AC (50 Hz) and 300
VA (maximum).
Connect the pump to the Pump terminals of terminal strip X4. The
post-circulation time of the circulation pump at the end of a heat
demand can be set according to requirements by means of a pro-
gram option at user level, see Section 9.1.6.
8.3.7 Connecting a PC
Using the optional Recom interface package a PC can be connec-
ted to the X7 "telephone connector".
Using the Recom software you can load, change and download
various boiler settings and readings.
See the user instructions supplied with the software.
