Questions and answers
Como funciona o aquipamento xee
The CLIVET WSAT-XEE Series is an air-cooled water chiller for outdoor installation. It works by cooling water through an evaporator and uses fans to remove heat. The unit operates in cooling mode by activating the compressor when the supply water temperature rises above a setpoint. It regulates temperature based on the supply water temperature. In heat pump versions, it can also operate in heating mode. The unit includes functions for ECO settings, thermoregulation, and alarm status. Proper installation includes water connections, insulation, and pressure controls to ensure efficient operation.

Como funcionam os comandos
The controls for the CLIVET WSAT-XEE Series work through a keypad and various parameters that manage unit operation, maintenance, and alarms:
1. Keypad Control: The remote keypad allows parameter adjustments. For example, parameter 49 enables second set-point control mode.
2. Maintenance Mode: Automatically maintains water temperature during standby by activating pumps and compressors. Controlled by parameters 42 (summer set-point), 44 (summer maintenance activation), and 45 (winter maintenance activation).
3. Alarms and Pre-alarms: Alarms are shown with flashing codes and are reset automatically once the issue is resolved. Pre-alarms show fixed codes and do not activate relays.
4. Compensations: Set-point compensations adapt unit operation to system needs, reducing compressor starts and protecting components. These include time- and charge-based offsets to delay compressor activation.
5. Glycol Operation: When using ethylene glycol, parameters like 32 (summer set-point), 77 (antifreeze resistance), 80 (antifreeze alarm), and 84 (pre-alarm threshold) must be adjusted.
6. Scan Time Logic: The system uses variable scan time to determine when to activate the compressor, based on temperature readings and set-point comparisons.
These controls allow efficient, automatic system operation while protecting components and maintaining set-point temperatures.
