Page 63: Control Overview
Monobloc Outdoor Unit Installation Manual 10.0 Control overview 10.1 Operating modes Occupancy mode: Depending on unit configuration, the system can be controlled in two ways. The first possible method embraces the use of setpoints, where the outdoor air temperature has no effect on the temperature set by the control. The second control method is based on a climatic curve. - Page 64 Monobloc Outdoor Unit Installation Manual When Cooling mode is selected, the chiller or heat pump will operate in the Cooling mode in order to cool the water loop to the selected temperature. When the heat pump is in Heating mode, the heat pump heats the water loop to the selected temperature. When the outdoor air temperature is very low, electric heaters or boiler heating can be used in order to satisfy the heating demand.
- Page 65 Monobloc Outdoor Unit Installation Manual 10.3.1 Predefined Climatic Curves: COOLING: If the cooling climatic curve [P586] is configured to “1” or “2”, the water setpoint will be calculated according to the selected cooling climatic curve. Two predefined cooling climatic curves are available: Climatic Curve Min.

Page 82: Maintenance
Monobloc Outdoor Unit Installation Manual 12.0 Maintenance Standard maintenance To ensure optimal efficiency and reliability of the units, we recommend establishing a maintenance contract with your local Service organisation. This contract will include regular inspections by Service specialists so that any malfunction is detected and corrected quickly, ensuring that no serious damage can occur. - Page 83 Monobloc Outdoor Unit Installation Manual Level 2 maintenance This level requires specific know-how in the electrical, hydronic and mechanical fields. The frequency of this maintenance level can be monthly or annually depending on the verification type. In these conditions, the following maintenance operations are recommended.
- Page 84 Monobloc Outdoor Unit Installation Manual To reduce waste, the refrigerant and the oil must be transferred in accordance with applicable regulations, using methods that limit refrigerant leaks and pressure drops and with materials that are suitable for the products. Any detected leaks must be repaired immediately. The compressor oil that is recovered during maintenance contains refrigerant and must be treated accordingly.
- Page 85 Monobloc Outdoor Unit Installation Manual Air heat exchanger We recommend, that finned coils are inspected regularly to check the degree of fouling. This depends on the environment where the unit is installed, and will be worse in urban and industrial installations and near trees that shed their leaves.
