Abstract

The control device has a pivotal flow control flap in a flow passage connected to the boiler flue. A switching system controlled by thermostats operate a motor which moves the flap between open and closed positions, a detector switching on the boiler burner when the flap reaches an open position. The switching system has a relay and the detector has two contact keys urged towards fixed contacts by respective springs but operated by pairs of cams on the shaft of the flap. The respective pairs of cams operate when the flap is closed and open and comprise diametrically opposite cams which are spaced 90 deg. w.r.t. the cams of the other pairs. The motor has a supply contact connected to the key which operates when the flap is closed, the fixed contact of this key being connected to the fixed relay contact, and connected to the fixed contact of the second key which is connected to the relay operating contact. The relay is powered when the thermostats are closed.
