cascade operating Information cascade operating Information The TriMax Boiler Management System includes a Cascade function which allows multiple Prestige boilers to operate together without the need for an external controller. One Prestige will be selected as the Master and will be wired to accept all the low voltage control signals. The other Prestige boilers will be designated as Slaves and will only have a communication cable connecting them to the other boilers in the Cascade System.

cascade Installation cascade Installation – System Piping Standard Cascade installations will utilize a balanced manifold system as the primary / secondary connection to the system piping as shown in Figure 6, page 26 or a reverse return piping arrangement as shown in Figure 8, page 28. Split Cascade installations will utilize a balanced manifold system as the primary / secondary connection to the central heating loop.
cascade Installation cascade Installation – cascade communication cable • A communication cable PTCAB01 must be installed between each boiler in the Cascade System. The cable has a 6 pin molex connector on one end and bare wires on the other end. The molex connector plugs into the Cascade Slave connector of the Slave boiler. The bare wires terminate on the Cascade Master terminals of the Master boiler or prior Slave boiler in cascades of three or more boilers.
cascade Installation • Power Supply – A dedicated 120 VAC / 15A minimum service must be used to power the boilers in the Cascade System. Multiple boilers in the Cascade System can be placed on the same electrical circuit. Each boiler can draw a maximum of 8 amps. • Alarm Wiring – The alarm contact closes whenever that particular Prestige is in a soft or hard lockout. The alarm contact will also close on the Master boiler when any of the Slave boilers are locked out.

cascade Settings Boiler Enabling algorithm The Master boiler uses the following algorithm to determine when the next boiler can be enabled: Number of Boilers Firing +1 x Minimum Firing Rate = Individual Boiler Firing Rate Number of Boilers Firing Once the currently fired boilers reach the calculated firing rate, the next boiler can be enabled without affecting the overall cascade firing rate.
cascade Settings cH or dHW Boilers default: 0 The CH or DHW Boilers setting specifies how many boilers in a Split Cascade System will respond to a domestic hot water call. The CH or DHW Boilers always include the Master boiler. The remaining boilers will only respond to central heating calls. This allows the Cascade System to satisfy both central heating and domestic hot water calls at the same time.
cascade Settings NOTICE only make adjustments to this setting after consulting Triangle Tube Technical Support. Improper adjustment of cH Proportional Gain could lead to temperature fluctuations and erratic cascade operation. cH Integral Gain default: 245 CH Integral Gain allows the cascade response to be adjusted for a central heating call. CH Integral Gain has the greatest influence when the system temperature is close to the setpoint.
cascade Settings - • To reach the setpoint faster, increase the DHW Proportional Gain value by 2. Perform Cascade Autodetection and initiate a domestic hot water call. Observe the cascade response and make further adjustments if necessary. decrease dHW Proportional Gain - The Cascade System will take longer to reach the setpoint, but setpoint overshooting is minimized. - If the setpoint is reached too quickly, decrease the DHW Proportional Gain value by 2.
cascade Settings NOTICE only make adjustments to this setting after consulting Triangle Tube Technical Support.
