Safety 1 Safety 1.1 About this manual This manual contains important information regarding the safe and appropriate commissioning and servicing of the Logamatic 4323 control panel. This manual is intended for heating contractors who, due to their training and experience, are knowledgeable in handling heating systems and domestic hot water installations. Only carry out service measures yourself if you have this technical expertise. 1.
1 Safety CAUTION! RISK OF INJURY/ SYSTEM DAMAGE 1.6 due to operator error! z Before switching the control panel on, check that its manual switches and those on the function modules are set to "AUT". Operator errors can cause injury and damage to property. z Make sure that children never operate the appliance unsupervised or play with it. z Make sure that only personnel trained to operate the appliance correctly have access to it.
Product description and scope of delivery 2 Product description and scope of delivery 2.1 Product description 2 The digital Logamatic 4323 control panel can be used as a stand-alone heating zone controller managing the heat generated by a manually or indirectly-fired buffer tank, or as a substation, for the demand-dependent control of a supply pump. The heating zone control function is part of the standard equipment level (one heating zone with actuator).
