Spoke to tech support about boiler and dived into all manufacturer settings on boiler, made adjustments, tested, system operational, boiler is working with outdoor temperature sensor and regulating boiler temperature, but regulating at a low temp for energy savings but not really heating home properly, tech support stated the colder it gets outside the higher the boiler temperature will rise. Had customer talk to tech support for them to explain the same details to customer about what’s going on with boiler. System is operational, control system on boiler can be replaced with regular hydrostat Aquastat and add an additional Aquastat on indirect water heater if control does not fit customers needs for heat and hot water.
