4.6. Wide operating range.
This series of heat pumps is designed to operate in various temperature conditions.
• A new generation of environmentally friendly refrigerant R290 has been used, which is
harmless to the ozone layer.
• Heating in low outdoor temperatures: With a well-optimized installation, the device is
designed to perform optimal heating even in low temperatures.
•
To ensure full heat demand coverage and ensure energy security for the building in
case of device failure, the installation of a backup heat source in the form of an electric
heater with power specified in Installation manual is required. This is a necessary
condition to maintain the warranty.
• The KHY series heat pumps come equipped with a factory-installed communication module
(DTU). The module is used to read device operating parameters, enabling the manufacturer
to improve their product, enhance customer satisfaction, and achieve maximum device
efficiency in specific climates. The module does not record any sensitive data, such as
detailed locations. The data collected by the module is stored by an external entity.
Klima-Therm does not gather data obtained by the DTU module. Additionally, Klima-Therm
does not provide any application for remote control of the device using the DTU module, and
thus, it assumes no responsibility for customers creating accounts in applications provided by
external entities, their operations, or data collection.
The use of applications that support the DTU module is at the user’s own risk, and
Klima-Therm disclaims any responsibility for such actions.
• Klima-Therm does not provide any technical support for applications from external providers
that support the DTU module.
The refrigerant R290 is flammable and explosive. It is prohibited to install it in
environment where there are operating or potential sources of ignition
