* When the flow rate drops below the indicated limit (flow switch minimum water flow rate) the flow switch
issues an alarm, which may be reset only upon reaching the maximum indicated flow rate.
12.2 COLD WATER PRODUCTION (SUMMER MODE)
A minimum temperature of 5°C is allowed at the evaporator outlet: for lower temperatures, contact the
Technical Department. In this case contact our technical department to study the feasibility and assess the
changes to be made according to demands. A maximum temperature of 25°C can be maintained at the
evaporator outlet in steady-state operation.
12.3 HOT WATER PRODUCTION (WINTER MODE)
When the system has reached steady state, the water inlet temperature must not drop below 25°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 60°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.
12.4 AMBIENT AIR TEMPERATURE AND SUMMARISED 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.
