2.2 Description<br />
2 allures<br />
1. Three-position switch Auto / Manual / STB TEST<br />
1.1 Boilers fitted with a cascade board<br />
(package AD 135)<br />
11 8 9 1 10 13 6<br />
AUTO: automatic position<br />
This position allows automatic operation of the<br />
installation under the control of the Diematic-m<br />
Delta regulator.<br />
Manual : manual position<br />
The boiler disregards the commands coming<br />
from the cascade board. It is regulated by the<br />
boiler thermostats (item 5)<br />
1.2 Other cases<br />
- either in manual position : boilers not fitted<br />
with a room thermostat or a SV-matic weather<br />
compensator.<br />
- or in AUTO position: boilers fitted with a room<br />
thermostat or a SV-matic weather compensator.<br />
The manual position does not allow<br />
switching off the regulator.<br />
STB Test: temporary action to test the safety<br />
thermostat:<br />
Press the TEST STB switch and set the pump shutoff<br />
switch 2 to the "Summer" position.<br />
2. Double switch Burner/Heating pump:<br />
This double switch controls the burner and the<br />
heating pump.<br />
In the "Winter" position, both heating and<br />
domestic hot water are operating.<br />
In the "Summer" position, only domestic hot water<br />
is operating (if a hot water tank is connected).<br />
If the boiler is fitted with a SV-matic weather<br />
compensator or is part of a cascaded installation,<br />
both switches must be left on the Winter<br />
position.<br />
