Many thanks for your help C-S-T, the manual is a great assistance in knowing more about our model. very much appreciated. Joe

We have a Hot tub that came with the house we purchased. Generally all ok, but the controls have never had an overlay. It has buttons that seem to be; 'Pump or Jets' on / Lights On / Temp Increase / Temp decrease There are Leds under that show when the Pump or Lights or Heaters are on. The Topside is 110mm wide approx. x 40mm Oval I can see that the control plugs in onto the main PCB. This is marked GS Series. Model - MGS500Z My question is, what new unit can I use to replace the current Topside ? Looking at Balboa info, it seems I would need a VL200 - 4 button model 118852 Searching the internet doesn't bring any up for sale, so could I use another model ? Can I use a Topside with only 1 Temp button? Would the main PCB recognise other button versions and work correctly? Thanks in advance Joe
