Abstract
A pre-startup control method for a boiler or water heater includes: providing a controller operatively coupled to a boiler or water heater unit; performing a unit shutdown operation; enabling a pre-start up mode; at about a same time or in any order, moving an air fuel valve by a controller to a non-off position with a gas supply to the water heater or boiler turned off, wherein the controller turns on a blower at an operational level, and causes an ignitor to spark; and displaying parameters which allow an affirmation of a safe and reliable ignition prior to a gas turn on of the boiler or water heater unit. A flow balancing method and a programmed auto run method are also described.
Claims13
A flow balancing method for a heating plant having a plurality of boilers or water heaters comprising:
- providing a controller having one or more processors operatively coupled to a plurality of boiler or water heater units of a heating plant, each unit of the heating plant including an isolation valve whose position is set by the controller;
- initiating by use of said controller an automatic flow balancing process;
- obtaining, by said controller, for each unit a current temperature rise (ΔT) defined as a water outlet temperature minus a water inlet temperature;
- and
- sequentially going through the plurality of units and, for each unit as it is gone through, automatically setting, by said controller, the position of the isolation valve of that unit responsive to the current temperature rise (ΔT) of the corresponding unit until that unit's ΔT-matches a common target temperature rise.
