Gas Boiler Series
Main Features:
1>. Low circulation water pressure protection: Minimum 0.5Mpa.
2>. Hot water temperature exceptional protection: Maximum 3oC/sec.
3>. Anti-frequently start ignition: An interval 3 minutes between next start.
4>. Multiple frost protection:
(A) ≤8oC pump circulate 30min.
(B) ≤5oC heating for 5min.
(C) lgnition fail no gas supply, pump circulate 24hrs
5>. Lighting strike protection.
6>. Deflagration protection: Increase gas flow automatically when gas pressure too low (lgnition time exceptional).
7>. Anti-lock water pump: 30 sec. /24hrs. Circulate automatically during summer.
8>. Ultra quite operation: C. E. Approved motor fan and pump.
9>. Self-diagnostic: Resume work from simply breakdown.
10>. Multifunctional user interface:
(A) Max. ~ Min. Gas flow control.
(B) The circulation water temperature difference control between outlet and return water.
(C) Hot water temperature exceptional protection control.
11>. Switch radiator heating and under floor heating.
12>. Switch water pump between 3 min. Circulatinig after intermittence 8 min. And 24 hrs during stand by.
13>. Adustable the circulation water temperature difference between outlet and return water (10~30) during stand by.
14>. Domestic hot water priority function.
15>. Avoid to rising temperature of domestic hot water when re-start tap by circulating hot water automatically after turn off the tap.
16>. 20sec. Exhaust waste gas before and after combustion
(3 sec. For domestic hot water funtion).
