Olsberg Storage heaters are equipped with a continu-
ous running charge control and a charge safety non-
resetting limit switch. If the charge control does not
switch off the elements under normal charging condi-
tions, the non-resetting safety limit switches off the
power supply to the elements. Problems in this cate-
gory must only be repaired by a qualified installer.
If the heater does not work correctly, the following
checks should be undertaken:
1. Heater does not store heat
Check the circuit breakers and relays.
Check whether the charge control or non-resetting
safety control has switched off. The safety control is
reactivated by pushing in the activating knob. Possible
causes of the heater switching off are:
- defective charge control thermostat
- prohibited covering of the heater causing hot-spots
2. Heater always goes on full charge
Charge control defect?
Check that the core sensor sits correctly in its sleeve.
3. Heater does not give out enough heat
Heater sized too small.
Fan or room temperature control is defective.
Has the fan been cleared? If the green LED control
light is not on, the fan has not been cleared.
Are the fuses for the fan circuit on the current distribu-
tion board loose or defective?
