How to troubleshoot a Trinity boiler with Er3?
1. Check wiring to Water Sensor for open circuits or shorting to ground (i.e. water). (Note: ER3 will be displayed if temperature sensed is less than 0?F.) 2. Replace Water Sensor if the resistance is not in the correct range. “24V Limit Error” Sentry has sensed a lack of 24V on the outlet of the Sentry burner relay (Bl).
What is the code for the NTI Trinity boiler?
The installation of the NTI Trinity Ti gas boiler must conform to the requirements of this manual, your local authority, and the National Fuel Gas Code ANSI Z223.1 and or CAN/CGA B149 Installation Codes.
Why is the air switch open on my Trinity boiler?
Indicates that the Sentry control has lost communication with an internal processor, contact NTI for assistance. “Air Switch Open” This is displayed when the boiler is expecting the air switch to be closed by a differential pressure generated when the combustion blower turns on.
What kind of propane does Trinity boiler use?
The Trinity Ti is factory set to operate with Natural Gas. BEFORE OPERATING WITH PROPANE, the specified LP Conversion Kit must be installed to convert the appliance so it will operate safely with LP Propane. Listed below is the correct Natural to LP Propane Conversion Kit number for Trinity Ti100-200 boiler models.
1. Check wiring to Water Sensor for open circuits or shorting to ground (i.e. water). (Note: ER3 will be displayed if temperature sensed is less than 0?F.) 2. Replace Water Sensor if the resistance is not in the correct range. “24V Limit Error” Sentry has sensed a lack of 24V on the outlet of the Sentry burner relay (Bl).
What should the water temp be in a Trinity boiler?
“Water Temperature Excessive” Sentry has sensed a water temperature in excess of 250°F at the water temperature thermister. 1. If the boiler is extremely hot chcck for adequate water pressure and circulation, contact NTI for assistance. 2.
Indicates that the Sentry control has lost communication with an internal processor, contact NTI for assistance. “Air Switch Open” This is displayed when the boiler is expecting the air switch to be closed by a differential pressure generated when the combustion blower turns on.
Do you need low water pressure switch ON TI 100-200 boiler?
If operation is unsuccessful and the error reoccurs continue to step 2. 2. Ti 100-200’s are equipped with a low water pressure switch on the boiler return that requires a minimum of 10PSI to complete the 24VAC ignition circuit.
