Instructions for the use of the documentation Instructions for the use of owner’s manual Before first use, read owner’s manual thoroughly and learn its content. You will learn the purpose, functions and the handling procedures for the device. In case of malfunctions of the heating system first consult Section(Disruptions in operation, alarms and troubleshooting) and consult your installer who will find the reason for the malfunction and resolve it.
Page 7 Instructions for the use of the documentation Glossary of used terms and conceptions In case of unfamiliar terms in the document you can find the explanation here. - ALTERNATIVE SOURCE: The heat source is used for systems with solar collectors, masonry heaters and wood stoves when we either do not have a heat source on hand at any moment or an automatic switch through the signal from the controller of the device (i.e.
Page 8: Termotronic™ Controllers
TERMOTRONIC™ controllers TERMOTRONIC™ controllers General TERMOTRONIC™ is a self-adapting controller for controlling the heat pump (hereinafter the DEVICE) and the heating system. It controls the operation of the device so as to ensure the most effi- cient way to produce the desired temperature of the building based on the needs of the heating sys- tem and outside temperature.
Page 9 TERMOTRONIC™ controllers Activating the device After switching on the main switch or installation breaker the interface screen displays the current state of the device - standby for the short delay time. The device is not operational yet. Standby........ Heating 35.5°C Return 35.3°C 49.0°C...
Page 10 TERMOTRONIC™ controllers Standby The device enters standby state when the values of the selected parameters Heating, Cooling, DHW, device protection ... are reached. The display of the interface displays the status: Standby........ Heating 35.5°C Return 35.3°C 49.0°C NOTE The device enters the standby mode also when any operation protection is active (compressor start-up delay, insufficient water flow).
Page 11 TERMOTRONIC™ controllers Power outage In case of a power outage the device ceases to operate. After power is restored the device under- goes 300 seconds of protection mode and then automatically returns to the mode before the power outage. In the case of a power outage the controller retains all settings set before the outage. NOTE In case of a power outage longer than 2 hours air-water models with a water connection, water has to be drained from the connecting pipes between the external and internal device.

Page 14: Quick Settings
Quick settings Quick settings NOTE The parameters of the TERMOTRONIC™ controller were set according to project documentation of the heating/cooling system, recommendations of the manufacturer of the device and your requests by the authorized contractor. At handover, the contractor is obliged to thoroughly present you with the possible ways of the device’s operation and explain the setting modes of the parame- ters important for the user.
Page 15 Quick settings NOTE - The space corrector influences the whole heating circuit and not the temperature of the individual room. The desired room temperature where the spatial corrector is located in the reference tem- perature for all other rooms of the heating circuit controlled by this spatial corrector. This is why it must be located in a room where the desired temperature is as close to the desired average tem- perature of other rooms (halls, living room).
Page 16 Quick settings NOTE You can find a detailed description of settings and additional functions in the manual for the spatial corrector KT-1. • Setting the room temperature with a room thermostat For setting the room temperature with a room thermostat consult the manual which come with the thermostat or consult the installer.
Page 17 Quick settings By setting the parameter C/W you set the number of temperature steps for which you want to raise or lower the temperature of heated water. You perform the settings in the following steps: Press key (MENU) in the basic menu. Standby........
Page 18 Quick settings For advanced changing the temperature of the heated water control mode of the heating system see Chapter(Heating setting). NOTE - The temperature of heated water can be raised or lowered for no more than four temperature steps. - The heating and individual circuits settings are separated from the cooling, this is why all settings for heating remain unchanged with the change of the mode into cooling.
Page 19 Quick settings Setting the temperature of DHW The device heats the water in a DHW via heat exchanger. In the case of the need heating DHW, the controller switches the device from heating the building to heating DHW. Heating DHW has priority over other modes of operation.
Page 20 Quick settings Changing the operational mode - winter/summer mode The mode of operation - winter or summer, is chosen according to season. In the time when you do not need heating or want to cool the rooms, switch to summer operating mode. In case heating is needed, switch to winter mode.
Page 21 Quick settings • Changing the operating mode Changing the operation from winter to summer mode is performed in the following steps: Press key (MENU) in the basic menu. Standby........ Heating 35.5°C Return 32.3°C 49.0°C In the user interface, use the key >...
Page 22 Quick settings Setting the cooling temperature In the operating mode (Summer, AUTO) which enables cooling you can adjust the temperature of cold water for the cooling circuits. The controller only enables the mode of controlling the temperature of cold water with maintaining constant temperature. NOTE For setting the cooling of the building the Summer or AUTO Mode must be chosen.
Page 23 Quick settings NOTE - The cooling and individual circuits settings are separated from the heating, this is why all settings for cooling remain unchanged with the change of the mode into heating. - In the case of floor, ceiling or wall cooling appropriate settings and protection have to be ensured in order not to cause surface condensation.

Advanced settings Advanced settings In this chapter you will find: - How to set the parameters of the device in case the system has no spatial corrector or thermostat built in or the settings for the temperature of heating water do not suffice the heating needs. - How to set the control mode of the heating water.
Page 27 Advanced settings NOTE - Heating circle 1 (M5) can only be a direct heating circle (without mixing valve). For this circuit we always choose the heating circle which requires the highest temperature (i.e. radiators). - Heating circuits 2, 3 and 4 (M6, M9, M11) can be direct (without a mixing valve) or mixing cir- cuits.
Page 28 Advanced settings Control modes for heating water have to be set separately by type in menus: ► Heating………………… ► 1. Circuit, ► 2. Circuit, ► 3. Circuit, ► 4. Circuit, Here it is necessary to take account the final NOTE! The method of adjustment is the same in all cases and is described on the example of heating curve in Section (Weather controlled heating) and on the example of control at constant temperature in Section (Heating based on constant tempera- ture)
Page 29 Advanced settings • Weather controlled heating Weather controlled heating means water temperature in the heating system is adjusted to the cur- rent air temperature. The lower the external temperature, the higher the losses and as a result a higher temperature of heating water is needed in the heating bodies (floor, wall or radiator heat- ing...) to compensate for the losses.
