Heating Water Production (Winter Mode) - MAXA i-290 0106 Installer Manual

13.3 HEATING WATER PRODUCTION (WINTER MODE)
When the system has reached steady state, the water inlet temperature must not drop below 22°C: lower values, not due to transient phases
or reaching steady-state, can cause system failures and could possibly break the compressor. The maximum outlet water temperature must not
exceed 75°C.
There could be failures to the regular operation of the unit or, in more critical cases, the safety devices could be triggered due to temperatures
higher than those indicated, especially if coupled with reduced water flow rates.
13.4 AMBIENT AIR TEMPERATURE AND SUMMERY TABLE
The units are designed and built to operate in summer mode, with condensation control, at outdoor air temperatures between -10°C and +46°C.
In heat pump mode, the allowed temperature range of the outdoor air is from -20°C to 40°C depending on the outlet water temperature as
shown in the table below.

Below are the graphed operating limits for heating, cooling and domestic hot water production. Please note that operating the unit outside the
operating limits given causes blocking alarms that lead to the product shutting down, with possible damage to components and/or safety organs.
