DESCRIPTION
Compressors
- Hermetic SCROLL type - Electronic motor overheating protection - Crankcase heater - Mounted on anti-vibration mounts
OF THE MAIN COMPONENTS
Connect Touch control module
- User interface with 4.3 inch touchscreen - Intuitive, user-friendly navigation using icons - Clear text display of information available in 5 languages (F-GB-D-E-I)
Water type heat exchanger
- Brazed-plate exchanger - Evaporator or condenser mode exchanger on the reversible heat pump version - Plate patterns optimised for high efficiency - 19 mm armaflex thermal insulation
The electronic control module performs the following main functions: - Regulation of the water temperature (at the return or at the outlet) - Regulation of the water temperature based on the outdoor temperature (water law) - Regulation for low temperature energy storage - Second setpoint management - Complete management of compressors with start-up sequence, timer and runtime balancing - Self-adjusting and proactive functions with adjustment of drift control for parameters - In-series staged power control system on the compressors according to the thermal requirements - Management of compressor short-cycle protection - Frost protection (exchanger heater option) - Phase reversal protection - Management of occupied/unoccupied modes (according to the time schedule) - Compressor and pump runtime balancing - Management of the machine operation limit according to the outdoor temperature - Sound level reduction device (night mode according to the user programme) with limitation of compressor capacity and fan speed - Diagnosis of fault and operating statuses - Management of a fault memory allowing a log of the last 50 incidents to be accessed, with operating readings taken when the fault occurs - Master/slave management of the two machines in parallel with runtime balancing and automatic changeover if a fault occurs on one machine - Weekly and hourly time schedule for the machine, including 16 periods of absence - Pump standby based on demand (energy saving) - Calculation of the water flow rate and operating pressure (hydraulic module version) - Electronic adjustment of the water pump speed and water flow rate (variable speed pump option) - Display of all machine parameters (3 access levels, User/ Maintenance/Factory, password-protected): temperature, setpoints, pressures, water flow rate (hydraulic version), runtime. - Display of trend curves for the main values
