I am hoping someone can help me.
I have an pool/spa combination that is controlled by an Intermatic RC2163FE Remote Control Pool to Spa Controller. Here is a link to the manual

It has been working fine for 2 years, but now the heater setpoint does not change between pool and spa mode when the remote spa switch/timer is activated. The pump motor and automatic valves are activated properly, but the heater setpoint no longer switches to spa mode.
There is a heater selection switch in the enclosure. The 3 amp fuse is ok. I suspect that there is a relay gone bad, but I can't seem to find any replacement parts anywhere. Does anyone have any suggestions of what to test or what I need to change out?
