Excellent service from Colin.
Upon arrival I was told that Hydronic System wasnâ€™t heating properly. During diagnostics customer turned heat on at both hydronic zones. Taco zone control getting signal and closing contacts. 120v going to both circ pumps but #2 not running. Switched from med speed to high speed and pump started running. Amp draw is very high, almost double the rated specs. Circ pump #1 at .51 amps while circ pump #2 at 1.01 amps. Spoke to Alex and he informed me that we did not install the Hydronic system. Quoting customer to replace 3 speed Grundfos Pump Type UPS15-58FC. Customer also Explained that unit 2 fan will run in heat mode but system is hydronic heat only. Went into thermostat settings and found airflow set to 500cfm when heat on. Turned off and tested hydronic settings. Unit operating normal at this time. Customer is going to speak to builder and plumber about who installed Hydronic system. Quoted customer to replace pump but she will get back to us. Per Alex, fee for today is waived.
