Installation Guide

1. Connection of the thermostat with a voltage relay 230V (e.g. VS30/RT200/ERT20/ERT30/
ERT50/VS10) to a gas boiler which requires free-voltage output NO/COM.

2. Connection of the SALUS temperature regulator with NO/COM relay (e.g. 091FL) with a
boiler control which requires NC/COM output ( NC/COM output is normally required in solid
fuel boilers controls).
