Boiler operation by user
8.1
General description
The boiler is equipped with a control unit LMS14. To set the parameters, use the display AVS37. For the proper
operation of the boiler, it is important to observe the hydraulic connection. For these purpose, design
documentation is prepared. The boiler is factory set so that it heats to the set temperature of the boiler (parameter
742). Switching is via a jumper at the input H5. When connecting the switching room unit to the input H5, the
jumper should be removed.
It is also recommended to use an outdoor sensor, due to weather-compensated heating and time programs use.
Further, we recommend using a communication room device according to the menu, see chap. 6.3.
Using the expansion modules, the control unit can manage up to 3 mixed heating circuits, hot water, cascade,
solar, pool, wood-fired boiler etc. (see VIADRUS design documents).
Another possible method of the boiler switching boiler is using 0 - 10 V via the input H1. The boiler is then only a
heat source.
