I purchased this product several months ago of a remodel and it was installed by my plumber/contractor while we were on vacation. Upon reading all the info about the heater, etc., my readout only has the motor on/off and chromatheraphy read out but no temp for heater. Am I missing something? I see the heater under the tub mount but it's not connected. Tub is Mod BP87 serial No. BCY3BJ Thanks in advance for a promo response - Please- MM
