Tekmar 268 manual

The Boiler Control 260 is designed to control a single stage heat source in order to provide outdoor reset or Domestic Hot Water (DHW) operation. The control has a Liquid Crystal Display (LCD) to view system status and operating information. ROOM - Set to desired room temp. outdoor temp. is able to fire. boiler manual. The minimum & maximum boiler output is expressed in MBtu/h. 1 MBtu/h = 1,000 Btu / hour. The range is from 10 MBtu/h to 9,990 MBtu/h. For example, if a boiler has a maximum output of 100,000 Btu / hr & a minimum output of 20,000 Btu / hr (turn down ratio of 5): Maximum Boiler Output = 100,000 = 100 MBtu/h 1,000 tekmar Control Systems Ltd., Canada; tekmar Control Systems, Inc., U.S.A.; tekmarcontrols.com Head Office: 5100 Silver Star Road, Vernon, B.C.
