Inquiry for Upgrading to Digital/Smart AC Controller - Request for Quotation

Kia ora, I hope this email finds you well. I am reaching out to inquire about the options and associated costs for upgrading my current air conditioning system from an analog controller to a digital or smart controller. I have attached a photo of the existing analog controller, and the unit is Temperzone HW 123CE-S. I would greatly appreciate it if you could provide me with the available options and qoutation for each of them. Thanks, and I look forward to hearing from you. Nga mihi, Muhammad Zaky ---
