Fan coil thermostat with multiple energy-saving modes

Abstract

The invention discloses a fan coil temperature controller adopting multiple energy saving models. The temperature controller comprises a control processing module, and a power module, a Lonworks intelligent receiving and dispatching module, a relay control module, an electricity quantity metering module, a temperature acquisition circuit, a keyboard circuit, a liquid crystal display circuit, a data storage and real-time clock circuit and an IO (Input / Output) expansion circuit which are respectively connected with the control processing module; the electricity quantity metering module comprises a voltage and current sampling circuit and an electricity acquisition circuit; the relay control module is divided into four relay output paths; one of the four paths is in normally-open / close double-contract output which can be used for controlling a two / three-wire valve; the other three paths are in normally-open contact output and are used for controlling the high / intermediate / low-level operation models of a fan. The temperature controller can be used for automatically implementing multiple flexible energy-saving control models such as temperature adjustment control according to consumption reduction indexes so as to realize the aims of reasonably utilizing energy and reducing the energy consumption.

Description

technical field [0001] The invention belongs to the technical field of energy and energy saving, and in particular relates to a fan coil thermostat with multiple energy saving modes. Background technique [0002] With the improvement of people's awareness of energy saving, new requirements are put forward for the central air-conditioning system: 1. Household metering; since the central air-conditioning system adopts centralized supply and household use, metering has become an indispensable demand. Through metering, you can Realize reasonable charges and assessments, improve energy-saving awareness of users, and develop good energy-saving habits. 2. Network monitoring: Through network monitoring, you can know the operating status of each terminal, understand the energy consumption, and take appropriate energy-saving measures; through remote and automatic control, reduce waste. 3. Energy-saving management: through the control of the fan coil unit operating parameter settings,...
