tekmar 264 Boiler Control - Manual (Page 2)

© 2008 D 264 - 12/08 2 of 32
The control uses a Liquid Crystal Display (LCD) as the method of supplying information. You use the LCD in order to setup and
monitor the operation of your system. The control has four push buttons ( Menu, Item,
▲ , ▼ ) for selecting and adjusting settings. As
you program your control, record your settings in the ADJUST menu table which is found in the second half of this brochure.
This brochure is organized into four main sections. They are: 1) Sequence of Operation, 2) Installation, 3) Control Settings, and
4) Testing and Troubleshooting. The Sequence of Operation section has six sub-sections. We recommend reading Section A:
General of the Sequence of Operation, as this contains important information on the overall operation of the control. Then read the
sub sections that apply to your installation.
The Control Settings section (starting at DIP Switch Settings) of this brochure describes the various items that are adjusted and
displayed by the control. The control functions of each adjustable item are described in the Sequence of Operation.
