Toyotomi FST i/o 460 Service manual E1 error

[piashaw]

Hi does anybody have a service manual for this Floor Standing Unit 60000Btu.

It's occasionally coming up with an E1 error when the fan is on LOW and it is in HEAT mode, otherwise it works fine. The unit was moved recently by somebody else so maybe problems were created by them BUT on the otherhand this may have been actually faulty for a long time, as they normally had it on full fan all the time. Somebody putit recently into auto fan mode and it errored out when the fan dropped to low!

Thanks in advance

Any takers?
