Arrived, met with Robert and proceeded to replace the outdoor temperature sensors. We programmed the sensors to the Wi-Fi interface module. Once the sensors were recognized we continued to replace and program the new thermostats. We confirmed that all systems were communicating and responding to the temperature changes. We also reached out to Honeywell tech support to assist in the programming process. Job completed. Robert was satisfied with the service, but irate that no receipts get sent via email or by courier. Robert is adamant about receiving his receipt’s.
