AVANT electronic control
This electronic module comprises a microprocessor control board and a TCO user terminal, and provides the following functions: Selection of the operating mode: cooling, heating, automatic, ventilation and dehumidification. Setpoint changes. Continuous monitoring of operating parameters. Display of values measured by the sensors. Compressor time delays. Defrost management (on heat pump units). Control of the supply air temperature. Setpoint compensation based on the outdoor temperature. Diagnostic of faults and general alarms. Counters for the number of starts and the unit components' runtime. Daily and weekly time schedule. Optional functions: Control of auxiliary electrical heaters. Proportional control of a hot water coil. Detection of fouled filters. Connection to a centralised management system (CMS). As an option, this electronic control can incorporate a pGD1 maintenance terminal, which facilitates initial programming of the unit, modification of operating parameters and a description of the alarms produced.
