Installation and Operation Instructions
Ti Series
36
11.0 WIRING
All wiring must be in accordance with the Canadian Electrical code, CSA C22.2 and any applicable local codes. Ensure that the
wiring complies with this manual. The boiler must be electrically grounded in accordance with the National Electrical Code
ANSI/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 any
electrical box within the unit. Ensure the power remains off while any wiring connections are being
made. 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 wiring
through the cabinet wall. Failure to follow instructions may damage unit.
Line Voltage Connections
The Trinity Ti line voltage junction box is located in the upper right corner of the boiler cabinet near the wall; the junction box is
accessed by removing the front door of the boiler, followed by the removal of the line voltage junction box cover. Each boiler is
provided with one hole and two knockouts for routing field wiring into the line voltage junction box. Line voltage field
connections are to be installed in accordance with Figures 11-1 and 11-2 for non-Combi and Combi Trinity boilers respectively
and Table 11-1.
Fuse (120VAC)
– The Trinity Ti Sentry controller is equipped with one 15 Amp fuse to protect the 120VAC pump outputs. The
fuse 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 use
wire grommets suitable for securing the wiring and preventing chafing. Failure to follow instructions
may result in component failure, serious injury or death.
Power Supply
- The Trinity Ti is designed to be powered using a single phase 120VAC power supply
that is fused (or protected via a circuit breaker) to allow a maximum of 15 Amps. Failure to follow
instructions may result in component failure, serious injury or death.
Labeling
- Label all wires prior to disconnecting them when servicing controls. Wiring errors can cause
improper and dangerous operation. Failure to follow instructions may result in property damage or
personal injury.
Continuity
- Before connecting the line voltage wiring, perform a continuity check between all wires
and ground to make sure that there are no electrical leaks that could blow a fuse or damage electrical
components. Also check the polarity of the line and neutral wires. Line must measure 120VAC to ground; neutral must measure
zero. Failure to follow instructions may damage the unit.
Max Load
- Circulator outputs Ap (Purple) and C1 (Blue) are each limited to operating a circulator
with a maximum current load of 3 Amps or a maximum 1/6 hp motor.
Low Voltage Connections
The Trinity Ti low voltage (thermostat) connections are located on the top-right on the outside of the boiler cabinet. Low voltage
field 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 the
Sentry controller. Power cannot be applied to these terminals, nor can the low voltage power supply
from these terminals be used to power anything, i.e.
DIGITAL THERMOSTATS CANNOT
be directly connected to the boiler
T-C terminals.
