Therma V R32 Installation Instructions.

Error Codes.

CH14 First two weeks: Blocked filters and/or air pockets Flow rate alarms are likely to occur during the first two weeks after commissioning; this is due to the formation of air-pockets which may occur and temporarily affect the flow-rate. In most cases, the air will migrate to the auto-air vents (AAV) and release without any requirement for intervention. Equally, if any sediments are in the hydronic pipework, they will be caught by the internal strainer. Blockages in the strainer can cause CH14 alarms. In this case, the strainers will need to be cleaned Recommendation: once the unit has been installed, advise the customers that it is quite likely and normal for a CH14 alarm to occur in the first two weeks. This will give the customer reassurance if and when the fault does arise! If the cause was air, then a simple power reset could allow the system to continue working as normal, once the pocket of air has made its way to the AAV TANK MODE ONLY Fault arises during: Testing each mode separately can help you to deduce where the fault lies 1.
