Alde's TPS5000 Frost Protection
All you people with the Alde wet central heating system (3000/3010) may be interested to hear about the TPS5000. This is an optional controller available from Alde. In addition to its features of allowing 7 day variable control over heating on/off times and temperatures there is a little known feature called frost protection.
Once configured, frost protection will automatically fire up the Alde whenever the MH internal temperature drops below the factory set 5 degrees centigrade (or any other value you care to set) Over the past couple of weeks this little accessory has kicked in and protected our MH from any potential frost damage with no intervention from ourselves and at very little cost.
It works on any of the Alde Compact systems so owners of Carthago, Concorde, Dethleffs, N+B, Autocruise, Frankia and others can protect their investments at little cost with no need to drain systems etc.
