2 . GENERAL DESCRIPTION OF THERM 28 KD BOILERS The THERM 28 KD gas boiler is made up of a supporting frame to which all operative elements are attached. In the upper part of the frame there is a stainless compact condensation device Giannoni that connects the combustion chamber with the burner and the two-chamber exchanger. - Page 4 The control panel is all made of plastic. On the front side there are the control elements (see the instructions for operation), in the inside there is the DIMS03-TH01 automatics containing the microprocessor controlling the boiler operations and the electric circuits participating in the ignition of the burner. Important: The type of supply of the ionizing current is determined by the neutral.

♦ POSITION OF THE BOILER The THERM 28 KD boilers may be placed both in the interior and in the non-residential areas of a house (in a boiler room, etc.). When placing the boiler inside a flat it is recommendable to set the limitation of maximum boiler output at the lower level of the power loss range and reduce thus the noise that the boiler makes when being operated at a lower output level. -

If the calculated expansion volume is higher than the volume of the expansion vessel in the boiler it is necessary to install another expansion vessel in the system. -

CM 27, CM 67, popř. T 8360A1000, TG - TM 100/19 and others. For the weather compensated regulation there is the outside sensor THERM Q01 offered by Thermona. A high-quality regulation can be achieved by using a smart programmable regulator SIEMENS QAA 73.110 that is continuously communicating with the boiler microprocessor via the IU02 interface. -
Page 9: Starting The Boiler
Recommendation: We recommend that the operation of boilers without weather-compensated regulation be controlled at least by a basic room thermostat. The room temperature is constant and it keeps the boiler in longer operation modes. It is also recommended to set the boiler thermostat for 60 ºC in autumn and spring and for 80 ºC in winter. It is advisable to use the inbuilt weather-compensated regulation that can be also complimented by a room thermostat, as it is suggested bellow. - Page 10 Setting-up of the heating temperature – revolving knob used for setting-up of the outlet water temperature in the heating system ranging from 30 – 80 C. When operating the boiler in the mode of weather-compensated regulation, the shift of heating curve is set in the range of ± 15 °C from the curve of weather-compensated regulation.

- Page 13 From what can be seen above it is clear that by means of the adjusting revolving knob that is used for setting-up of the heating temperature on the control panel we can set the temperature of the heated environment at the required level.

∗ A repeated check of the through-flow switch is activated whenever it does not switch within 15 sec after the pump started to operate. The pump halts and when another 45 passes, another attempt to start the boiler is made. This is repeated ten times. -

In these cases the service company may also require that the customer pay for the repairs. THERMONA spol. s r. o. provides a 24 months guarantee that is due to start at the time when the boiler is put into operation for the first time. -
