Trinity │Installation and Operation Instructions Ti Series3611.0 WIRINGAll wiring must be in accordance with the Canadian Electrical code, CSA C22.2 and any applicable local codes. Ensure that thewiring complies with this manual. The boiler must be electrically grounded in accordance with the National Electrical CodeANSI/NFPA 70, local codes, and/or the Canadian Electrical Code CSA C22.1.Avoid Shocks - To Avoid Electrical Shock, turn off electrical power to the boiler prior to opening anyelectrical box within the unit. Ensure the power remains off while any wiring connections are beingmade. Failure to follow these instructions may result in component failure, serious injury or death.Field Wiring - Wire grommets must be used to secure wiring and prevent chafing when passing wiringthrough the cabinet wall. Failure to follow instructions may damage unit.Line Voltage ConnectionsThe Trinity Ti line voltage junction box is located in the upper right corner of the boiler cabinet near the wall; the junction box isaccessed by removing the front door of the boiler, followed by the removal of the line voltage junction box cover. Each boiler isprovided with one hole and two knockouts for routing field wiring into the line voltage junction box. Line voltage fieldconnections are to be installed in accordance with Figures 11-1 and 11-2 for non-Combi and Combi Trinity boilers respectivelyand Table 11-1.Fuse (120VAC) – The Trinity Ti Sentry controller is equipped with one 15 Amp fuse to protect the 120VAC pump outputs. Thefuse is located under the cover of the Sentry 2100 control.Wire Protection - When passing any wiring through the cabinet of the boiler, the installer must usewire grommets suitable for securing the wiring and preventing chafing. Failure to follow instructionsmay result in component failure, serious injury or death.Power Supply - The Trinity Ti is designed to be powered using a single phase 120VAC power supplythat is fused (or protected via a circuit breaker) to allow a maximum of 15 Amps. Failure to followinstructions may result in component failure, serious injury or death.Labeling - Label all wires prior to disconnecting them when servicing controls. Wiring errors can causeimproper and dangerous operation. Failure to follow instructions may result in property damage orpersonal injury.Continuity - Before connecting the line voltage wiring, perform a continuity check between all wiresand ground to make sure that there are no electrical leaks that could blow a fuse or damage electricalcomponents. Also check the polarity of the line and neutral wires. Line must measure 120VAC to ground; neutral must measurezero. Failure to follow instructions may damage the unit.Max Load - Circulator outputs Ap (Purple) and C1 (Blue) are each limited to operating a circulatorwith a maximum current load of 3 Amps or a maximum 1/6 hp motor.Low Voltage ConnectionsThe Trinity Ti low voltage (thermostat) connections are located on the top-right on the outside of the boiler cabinet. Low voltagefield connections are to be installed in accordance with Figures 11-1 and 11-2 for non-Combi and Combi models respectfully,and Table 11-2.The Trinity Ti Low Voltage connections use a low voltage DC signal for communicating inputs to theSentry controller. Power cannot be applied to these terminals, nor can the low voltage power supplyfrom these terminals be used to power anything, i.e. DIGITAL THERMOSTATS CANNOT be directly connected to the boilerT-C terminals.
