7.13 Instructions before commissioning
Before commissioning it is necessary to check:
The supply valve of the expansion tank. The pressure in the expansion tank has to be adjusted according to the
project of the heating system. The pressure in the expansion tank has to be checked during an annual regular
service inspection.
The air-relief valve of the heat-exchanger and the water heater. Upon deaeration, use, for example, a silicone
hose ø 6 mm, which is a part of the boiler, and a vessel for prevention from escaping water into the boiler control
unit.
Release the screw on the valve; in case that the system is aerated, air would start escaping from the heat-
exchanger. At the moment when water starts leaking, the heat-exchanger is considered to be deaerated, and you
may tighten the screw again. Repeat this procedure several times until the system is fully deaerated.
The automatic air-relief valve of the pump has to remain permanently opened.
The minimum water pressure in the heating system is 0,8 bar, the maximum operation pressure is 2,5 bar.
During watering and deaeration of the system it is necessary to adjust the pressure in the heating system to the
values according to the project of the heating system.
8 Operating the boiler by an user
8.1 General description
The boiler is equipped with a control unit LMS14. The display AVS37 serves for setting the parameters. It is
necessary to observe the hydraulic connection for correct function of the boiler. The project supporting documents
are developed for these purposes. The boiler is adjusted in the production plant so that it heats to the adjusted
boiler temperature (parameter 742). It is commutated by means of a jumper on the input H5. In case of connection
of the commutating space device to the input H5, it is necessary to remove the jumper.
We also recommend using an outdoor sensor by reason of equithermal heating and using time diagrams. Further
we recommend using a communicating space device according to the offer, see chapter 5.3.
The control unit is determined for control by means of extension modules of 1 to 3 mixing heating circuits, hot
water, a cascade, a swimming pool, a wooden boiler, etc. (see the project supporting documents VIADRUS).
Other possible method of commutation of the boiler is with help of 0 - 10 V through the input H1. In this case the
boiler is the only the source of heat.
