Tekmar 260 control malfunction

Hock Member Posts: 1
Help Have just installed a Tekmar 260 boiler control and I cannot get the control to power up my boiler. I do not have DHW system just a boiler with four zones. I have connected end switches, power supply, pump supply, outdoor sensor, boiler temperature sensor and boiler circuit. All are connected at the correct point of the control, the temp setting for the boiler is 180f to 160f, warm weather sensor is set for 60f. When power is applied to the control, screen shows circulator symbol and oil burner symbol but no power is available at the burner terminals. Is there something I am doing wrong? Thank you

    What do you have landed on terminals 11 and 12? Those terminals should be connected to "T-T" on boiler where the boiler supplies power and tekmar is a switch. What type of boiler? Single stage?

    The boiler terminals on the Tekmar are not power to start the boiler. It is only a set of contacts to start the boiler.
