34External Wiring2. Follow thermostat manufacturer’s instruc-tions for proper installation. Thermostatshould be located on an inside wall awayfrom any heat or cold influences such asdrafts, lights, fireplaces, etc.3. Set the thermostat anticipator (If applica-ble) as follows:- Set for 0.2 amps when wired directly tothe PRESTIGE.- Set to match the electrical powerrequirements of the connected devicewhen wired to zone relays or otherdevices. Refer to the relay manufactur-er’s specifications and the thermostatinstructions for additional informationon anticipator setting.The use of power stealing thermostatswhich draw their power from the PRES-TIGE can lead to erratic or unpre-dictable operation.Outdoor Sensor WiringThe Outdoor Reset function and WarmWeather Shutdown (WWSD) features requirethe connection of the included outdoor temper-ature sensor. See page 64 for outdoor sensorinstallation and setup.Domestic Hot Water WiringThe Domestic Hot Water terminals can accepteither a call from an aquastat (switch) or tem-perature sensor. Use of the included indirectwater heater sensor is recommended.1. Connect the DHW aquastat or temperaturesensor to the low voltage terminal strip onthe wiring panel below the PRESTIGE con-trol module, as shown in Fig. 19 on page 31.Additional Boiler LimitsAdditional boiler limits (High Limit, LWCO,etc.) can be wired into either the Manual ResetLimit or Auto Reset Limit terminals of thePRESTIGE. These limit connections will pro-vide a “hard” lockout requiring a manual resetof the PRESTIGE or a “soft” lockout in whichthe PRESTIGE will automatically reset whenthe limit resets.Manual Reset Limit and Auto ResetLimit connections to the PRESTIGErequire a dry contact with no externalvoltage present. Ensure no external volt-age is present on each set of wires beforeconnecting to the PRESTIGE. If exter-nal voltage is present, the use of an isola-tion relay is required to prevent damageto the TriMax controller.1. Remove the factory installed jumper wireon the Manual Reset or Auto Reset termi-nals that will accept the additional boilerlimit.2. Connect the additional boiler limit to thelow voltage terminal strip on the wiringpanel below the PRESTIGE control mod-ule, as shown in Fig. 19 on page 31.External Modulation ControlThe PRESTIGE firing rate can be controlled byan external modulating boiler controller. Seepage 65 for external modulation signal wiringand setup.NOTICENOTICE
