Trouble Shooting Tips

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 (see
Chapter "Important Instructions").
If the heater does not work correctly, the following
checks should be undertaken:
Attention:
In case a direct heating element or an integrated room
temperature thermostat is installed on a storage
heater, the rocker switch at the front panel is electri-
cally wired to other components. This wiring must be
disconnected if the front panel is removed for service
purposes. For this remove the right side panel and
the wiring. Follow the special instruction for the room
temperature thermostat.
1. Heater does not store heat
• Check the circuit breakers and power switches in
the control panel.
• Is there line voltage on the electronic charge
control B1?
• Is there line voltage on the „SH" terminal of the
electronic charge control B1?
• Is the protective resistance R1 (22 Ohm) defec-
tive?
• Is the thermal relay K1 switching correctly?
Note: Switching delay of up to 2 minutes.
• Has the high-temperature safety cut-out F1 activa-
ted? The safety cut-out is reactivated by pressing
the operating knob. Possible causes for high-
temperature safety cut-out are:
- defective charge thermostat
- prohibited covering of the appliance causing
overheating
• Check the heating elements.
• Check the charge potentiometer (charge intensity
regulator B4) (0 – 47 kOhm).
• Check that the core temperature sensor B2 is sit-
ting in the correct position and shows correct resis-
tance values.
• Check the control voltage on terminals A1/Z1 and
A2/Z2. The larger the control voltage, the less
charge will be taken by the heater.

2. Heater always on full charge
• Does the electronic charge control B1 switch off
the thermal relay K1? Check the charge potentio-
meter (charge intensity regulator B4) and the core
temperature sensor B2.
• Is the jumper bridge „Max. Charge" B3 wired cor-
rectly? See circuit diagram for specified values.
• Is the charge thermostat detective? If the heater is
being charged by a charge control (central charge
control), check the control voltage on terminals
A1/Z1 – A2/Z2. If there is no measurable line volt-
age on the terminals, the charge control is possibly
defective.
3. Appliance does not give out enough heat
• Chosen appliance is too small. Fan or room ther-
mostat is defective. The charge control may pos-
sibly need to be adjusted to a higher value. Follow
the special instructions in the corresponding
charge control manual.
• Is the fan running? Check the room thermostat, fan
safety cut-out F3 and if necessary the mechanics
of the fan itself.
