Summary
ZL-830 Digital LCD Room Thermostat is manufactured by adopting advanced chip submerged membrane technology, detect the room temperature through built-in high precision NTC sensor, and compare it with set temperature, blast with constant air volume or automatic variable air volume, stimuously control the on-off of the electric control valve automatically, so as to achieve the effect of indoor comfort. This series central air-conditioning room thermostats, is widely used to regulate temperature in industrial, commercial and family room. |
Technical datas：
1. Working voltage: 220VAC ± 10%, 50/60Hz
2. Power consumption: <1.5W
3. Load current: <3A
4. Temperature range: 10 ℃ ~ 30 ℃
5. Temperature accuracy: 1 ℃
6. Installation bolt center: 60mm (standard 86) 7. Timing boot and power off: 30min-24h |
Function and feature：
◆ Large-screen LCD display, easy to operate. ◆ Key pattern is laser ablation, will not fade.
◆ Built-in memory, automatic memory setting data and operational status before power failure, even in the case of sudden power off during working, the data will not be lost, it will automatically start at the original state, so the product is especially suitable for hotels and other important places.
◆ Three temperature control manners: automatic variable air volume, gear constant air volume, combined temperature control by electric control valve.
◆ Regular boot and shutdown within 24 hours or less.
◆ Using interval control techniques, greatly reduces the action number of electric valve, extend the life of the electric valve.
◆ 4-conditioned operating modes: heating, cooling, sleeping and ventilation.
◆ Can be equipped with all forms of electric valve.
◆ Set the cooling energy saving spot on the motherboard: set two welding spot on the main PCB board solder, disconnect under normal circumstances; When two points were connected, the minimum set temperature under cooling mode is limited at 26 ℃ (also confirm according to user needs)
