Gas Boiler Series

Main Features:

1>.Low circulation water pressure protection: Minimum 0.5Mpa.

2>.Hot water temperature exceptional protection: Maximum 3℃/sec.

3>.Anti-frequently start ignition: An interval 3 minutes between next start.

4>.Multiple frost protection:

     (A)≤8℃pump circulate 30min.

     (B)≤5℃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).
