Commissioning - Carrier 50CO Series Installation, Operation And Maintenance Instructions

11 - TECHNICAL SPECIFICATIONS
- Temperature or temperature and humidity room sensors:
The room sensors are mounted on a wall in the room to be regulated. The sensors are provided at the back of the unit.
For connections, please see the wiring diagram and the recommendations in the electrical specifications section.
- Changeover control
:
Surface-mounted onto the hydraulic circuit. This option allows the temperature of the water network to be monitored and the exchanger
(coil) to be operated in either cooling or heating mode (summer or winter mode).
- Supply air low limit
- Fire thermostat
11.2.9 - Lon gateway
This is incorporated in the electrics box.
The gateway is used to translate the main information available in MODBUS into LON.
It is possible to connect 1 to 5 units to the LON gateway.
Please see the recommendations for routing cables in the electrical specifications section and in the control manual (0037.03.2015).

12 - COMMISSIONING

After making the necessary electrical and hydraulic connections, carry out the unit commissioning, checking the following steps:
• Check the tightness of the electrical connections.
• Check the hydraulic connections (direction of inlet/outlet connections).
• Make sure the inside of the unit is clean and free from foreign bodies.
• Make sure the inside of the unit is clean and free from foreign bodies.
• Check the power supply voltage and heat protection rating in accordance with the currents for the various components.
• Check the siphon height.
• Vent the air out of the coils via the air bleed valves.
• Check the tightness of the circuits; retighten the valve if necessary.
• To configure the setpoints, please refer to the control manual. "CARRIER CCU Controller"
• Depending on the solution chosen, the air flow may be.
• adjusted based on the difference with the setpoint.
• constant.
(refer to the control manuals for the corresponding configurations)
• If a master-slave control system is used, make sure each unit is interconnected by a connection cable.
• Simulate a trip of the electrical components, controlled instruments and alarms.
• Check the current of each.
Standard components:
• Temperature alarm.
• Air flow alarm.
• Water leak alarm.
• Fan motor assembly.
Optional components:
• Temperature low limit alarm.
• Outer contact control.
• Electric heater.
• Humidifier.
• Hot water valve.
- Check the cleanliness of the humidifier supply water (option).
- After allowing the unit to run for a few hours, check the clogging level of the filter, especially in the case of an F7 filter.
