6.1 Control unit settings

The purpose of optimum control unit settings is to achieve long burner

run times and avoid rapid temperature changes in the boiler. Gentle

temperature changes result in a longer service life of the heating system.

The control strategy of the control unit must therefore be prevented

from becoming ineffective, i.e. through the boiler water regulator

switching the burner on and off.

▶ Maintain the minimum differential between the selected shutdown

temperature of the high limit safety cut-out, the temperature

regulator, the maximum boiler water temperature and the maximum

temperature demand ( table 13).

▶ Select set temperatures for the heating circuits that are as low as

possible.

▶ Start heating circuits (e.g. when starting up in the mornings) at 5-

minute intervals.

▶ Select temperatures ( table 13, page 26) at high limit safety cut-

out [1] on the control unit and at temperature controller [2].

▶ Select the maximum boiler water temperature at the MEC [3].

NOTICE: Risk of boiler damage through contaminated

combustion air.

▶ Never operate the boiler in very dusty conditions,

e.g. if building work is taking place in the installation

room.

▶ Ensure adequate ventilation.

▶ Never use or store chlorinated cleaning agents or

halogenated hydrocarbons (as contained in spray

cans, solvents or cleaning agents, paints and

adhesives, for example) in the boiler room.

▶ A burner contaminated during building work must be

cleaned before commissioning.

▶ All cover plates, enclosures, clean out ports, and

guards must be in place at all times, except during

maintenance and servicing.

▶ Never burn garbage or paper in the unit, and never

leave combustible materials around it.

The boiler may be operated with a Buderus Logamatic

control unit from the 4000 series.

The maximum boiler water temperature can be selected

on the control unit (MEC) in the "Boiler parameters"

menu, under menu item "Max. shutdown temperature".

If the Buderus Logamatic 4000 control unit is used,

burner modulation in standard mode is not enabled for 3

minutes. Never modulate upwards more quickly than

this.

The maximum temperature demand is not a value that is

directly selected. The maximum temperature demand is

composed of the set temperature and the rise.
