160 Interface Board Activation

0 = not active

1 = active

WARNING: Never change the de- fault setting without the Munchkin Interface Board installed.**

170 Interface Board Function

0 = Building Management

1 = Enables Tekmar Modulating control.

(Consult with Tekmar to assure the Tekmar Control is compati- ble)

181 Step Modulation – Regulates the burner output in 6 steps in one- minute intervals. This reduces short cycling.

19185° Indirect boiler set point (flow) Temperature default = 119° to 180°

201 Not applicable

The central heating demand is detected when the room thermostat closes. When an outside sensor is also connected, the supply tempera- ture will depend on the factory default central heating curve.

To set your heat curve you will have to set the following parameters

1.Minimum outside design temperature:

Function 8

2.Design Supply water temperature at the minimum design outside temperature:

Function 9

3.Maximum outside design temperature:

Function 10

4.Design Supply water temperature at the maximum outside temperature: Function 11

NOTICE

It is important to note that the homeowner can adjust the heat curve down by adjusting the central heating temperature to a lower setting.
