MCX Control System (OPTIONAL UPGRADE)
- Controller is composed of user interface and electronic board.
- Power supply : 20/30 Vdc –24 Vac.
- Panel mounting type.
- Screen with display that allows the inputs and outputs to be
visualized.
- Operating mode : 2 compressors, cooling only and heat pump.
- Defrosting by pressure transducers.
- Management of water circulating pump and hydraulic module.
- Clock programming.
- Programmable controller with 3 access levels: User,
Maintenance and Manufacturer.
Main Functions of the Control System
- Regulates wáter temperature
- Service hour counter for compressors and wáter pumps (optional)
- Intake and outlet water temperature reading displays, as well as, pressure reading displays in evaporator
and condenser stages
- Compressor start timers
- Pressure overload safety protection
- Electronic compressor protection
- External fan protection
- Water flow protection
- Anti-freeze active protection
- Remote ON/OFF
- Remote COOL/HEAT mode toggle
- Condensing and evaporating pressure control by incorporating 2 ventilation stages
- Check valve for cycle reversion (only available for Heat Pump units)
- Anti-frost feature. Anti-frost start and stop settings through pressure readings.
- Anti-frost duration time control.
2. Compressor
Hermetically sealed, alternative compressor with wide operation limits. Equipped with thermal protection, -
any other additional protection is not needed-, it includes its oil charge for the perfect lubrication and
internal shock-absorbing system. The compressor is mounted on the base with antivibration supports and
it is acoustically isolated, guaranteeing a silent and vibration-free operation.
3. Outdoor coils
Coils built with seamless copper tubes and expanded in aluminum fins. They incorporate a distributor with
neck and calibrated orifice (nozzle) to improve gas distribution in Cool mode.
4. Refrigerant-water heat exchanger
Stainless steel plate heat exchanger (AISI 316) welded with a bronze based technique. It’s perfectly
isolated with insulating material to avoid thermal exchange with its surroundings. It incorporates a resistor
to frost protection mode to avoid dangers of breaking by water freezing in case of lack of water flow.
5. Motorfan
Mounted on a square-based embouchure; with a circular opening, which is ideal for optimal aerodynamic
performance of air flow supplied by the fan. Weatherproof completely sealed and permanently lubricated.
They consist of aluminum blades designed for low noise, inserted into the outdoor rotor of a high-efficiency
motor with IP-54 protection and Class F coil insulation. Internal thermal sensors have built-in for their
protection and an external safety grate.
