Safety and Heating boiler on the instrument:
1- Digital Remote Control: (Turn on/off, stall.temperture and time adjustment )
2- Tank expansion (Adjust system pressure)
3- Heating Unit: ( for hot water )
4-Safety Relief Valve: ( Active at 3 bar gauge)
5-Pressure Switch: ( Prevents dry running of the instrument )
6- Barometer: ( Pressure gauge ) observe the water pressure of the tank expansion
7- Pump :a kind equipment which help the fluid to work normally in the system .
8.-Filter: the impurities of the water will isolate through the filter .
9.Safty Valve:it’s a protect equipment .
Features
Timmer function : Timmer functions meet different customer need . for saving compustion
Wide temp setting function: the water temp setting in range of 30-85degrees.
Over temp protection: When the heating element temp exceeds 95degrees.over-temp protector starts and boiler stop working .
Dry heating protection: when the heating element temp exceeds 110degrees, dry-heating protector start, disconnect the power supply ,then we should button “return”key by manual .
Leakage protection: when the system has leakage phenomenon.leakage protect function start and boiler stop working . Display screen display E2 .
Pressure gauge : Show system currently pressure (normal pressure will be 1-1.5bar)
Antifreeze function: when the system temp is below 3degrees,the system automatically start to heating .when temp heated 10degrees ,it will stop heating .

Manufactory Suggest :
Boiler with Underfloor system : Suggest to set 50degrees
Boiler with radaitors : suggest to set 70-75degrees
While we choose heating power, the fellowing conidtions have to be taken into consideration:
*While calculating demand for thermal energy, a number of factors should be taken into consideration:- building cubature- level of room ventilation- heat accumulation
-value of heat transfer through walls, windows and ceilings
