①室外溫度補償等多種控制策略：調節閥控制，二級管網供水溫度恒定運行， 二級管網供回水平均溫度運行，流量恒定運行，流量曲線運行，室外溫度補償，分時控溫運行。
① Outdoor temperature compensation and other control strategies: control of regulating valve, constant operation of water supply temperature of secondary pipe network, average temperature operation of supply and return level of secondary pipe network, constant flow operation, flow curve operation, outdoor temperature compensation, time-sharing temperature control operation.
②壓力控制：二級管網供回水壓差調節控制回路，二級管網回水定壓控制系統，電磁閥泄壓控制。
② Pressure control: secondary pipe network supply and return water pressure difference regulation control circuit, secondary pipe network return water constant pressure control system, solenoid valve pressure relief control.
③報警功能：一級管網回水溫度高限，二級管網供水壓力高限，二級管網供水溫度高限，二級管網回水壓力低限，二級管網供回水壓差低限，水箱水位高限、低限，循環泵變頻器故障，補水泵變頻器故障等情況，要求控制器能夠及時報警，并將報警信息遠傳至遠程監控中心。3151/3051法蘭式壓力變送器應用_智慧熱網供熱系統改造工程
③ Alarm function: high limit of return water temperature of primary pipe network, high limit of water supply pressure of secondary pipe network, high limit of water supply temperature of secondary pipe network, low limit of return water pressure of secondary pipe network, low limit of water supply and return water pressure difference of secondary pipe network, high and low limit of water tank water level, failure of circulating pump frequency converter, failure of frequency converter of make-up water pump, etc., the controller is required to alarm in time and transmit the alarm information to remote Monitoring center.
④補水箱液位控制：當水箱液位低于低限值時補水電磁閥自動開啟；當液位到達高限時補水電磁閥自動關閉，從而實現補水箱自動上水功能。
④ Level control of make-up water tank: when the water tank level is lower than the low limit value, the make-up water solenoid valve will open automatically; when the liquid level reaches the high limit, the make-up water solenoid valve will be closed automatically, so as to realize the automatic water filling function of the make-up water tank.
⑤電磁閥泄壓：當二級管網壓力超過設定值時，電磁閥自動通電打開泄壓；當壓力達到低限值時，電磁閥自動斷電關閉。
⑤ Solenoid valve pressure relief: when the pressure of the secondary pipe network exceeds the set value, the solenoid valve will be automatically powered on to open the pressure relief; when the pressure reaches the low limit value, the solenoid valve will automatically power off and close.
⑥聯鎖控制：二級管網回水壓力高于定壓值時，啟動變頻循環泵并做自鎖，進行二級管網供回水壓差調節，此時延時開啟一級管網電動調節閥進行二級管網供水溫度自動調節等保護措施。
⑥ Interlock control: when the return water pressure of the secondary pipe network is higher than the constant pressure value, start the frequency conversion circulating pump and do self-locking to adjust the supply and return water pressure difference of the secondary pipe network. At this time, delay to open the electric control valve of the primary pipe network to automatically adjust the water supply temperature of the secondary pipe network.
⑦斷電保護、來電啟動：控制器具備自我保護和自我診斷功能。當系統斷電時，將參數自動保存，來電后可以自動安全運行。
⑦ Power off protection, call start: the controller has self-protection and self diagnosis functions. When the system is powered off, the parameters will be saved automatically, and the system can run automatically and safely after calling.
⑧巡檢功能：為了實現無人值守熱力站的管理，有效管理巡站人員的巡站時間，要求在熱力站節能控制裝置設有巡檢簽到功能，巡站人員在控制裝置輸入員工編號，即可將巡站信息、巡站時間傳輸到中心監控平臺，有效地管理巡站人員。
⑧ Patrol inspection function: in order to realize the management of unattended thermal station and effectively manage the patrol time of station patrol personnel, it is required that the energy-saving control device of the heat station shall be equipped with the function of inspection sign in. The patrol personnel can input the employee number in the control device, and then the station inspection information and time can be transmitted to the central monitoring platform to effectively manage the station patrol personnel.
⑨數據儲存：當通信網絡由于外界客觀原因暫時中斷時，測控系統具有數據暫存功能，能夠每隔1min儲存1次測量數據，并儲存至少48 h的數據。當通信網絡恢復時，能夠自動通過網絡上傳或通過儲存介質上傳。
⑨ Data storage: when the communication network is temporarily interrupted due to external objective reasons, the measurement and control system has the function of data temporary storage, which can store the measurement data every 1 min and store the data for at least 48 h. When the communication network is restored, it can upload automatically through the network or through the storage medium.
