2. Remove the thermostat’s sensing bulb from the SMART drywell. Once the bulb is removed, coil the thermostat capillary tube and bulb against the bottom of the cover plate using care not to kink or damage the capillary tubing. GEnERal InfoRMaTIon This supplement requires the use of the IDWH Sensor Kit PSRKIT22. The IDWH Sensor kit should include the following parts: · NTC Sensor with wire leads and connections · Terminal block tool 3.
Wire of nTc Sensor to Prestige 1. Disconnect the Snap-set connector located on the thermostat cover plate of the SMART. One portion of the Snap-set connector will remain mounted on the cover plate. On the Snap-set plug portion not mounted, use a Phillips-head screwdriver and remove the plug cover mounting screws. 2. With the Snap-set plug cover removed, connect 18 gauge wire or thermostat type wire to the end terminals C and 1 of the plug.
NOTICE The following section applies to PRESTIGE Boilers using the Honeywell Type 3 McBa control. This control is identified as Honeywell McBa 14201. for PRESTIGE Boilers with Honeywell Type 5 McBa control (identified as Honeywell McBa 54201), reference pages 13 through 19.
To change a Parameter Setting NOTICE Use the + or - button to change the value of the display. once a parameter setting value has been revised and stored, if the STEP button is pressed for the next parameter setting the value setting of that parameter will appear. The display will not show The P_XX of the next sequential parameter. sequence of parameters may be scrolled through, as the display will roll over from parameter 46 to parameter 1. Press the STORE button once to save the change.
IdWH SEnSoR PaRaMETER WARNING 1. Once the access code number has been stored and accepted in the control module, change the display readout to “Parameter” mode by pressing MODE until the display shows Parameter 46 has several other possible settings available. The factory setting of the IdWH is aquas- PARA. tat control or _13. The required revised setting of the IdWH nTc control or _12.
dHW SETPoInT ValuE addITIon dHW on dIffEREnTIal To achieve a boiler operating temperature during a domestic request for heat the MCBA Control uses Parameter 1 and a second parameter, Parameter 21 DHW Setpoint Value Addition. Parameter 1 plus Parameter 21 will establish the boiler operating temperature. The MCBA Control Module has 2 differential settings for the burner operation when using the IDWH Sensor kit.
4. Press the + or - button until the desired “DHW OFF Differential” setting is achieved. Press STORE to save the setting. The display will flash when the revised setting is accepted. 5. Once the desired parameter setting have been revised and stored within the Prestige Control module, press RESET to exit the CODE mode. 4. Press the + or - button until the desired “DHW OFF Differential” setting is achieved. Press STORE to save the setting. The display will flash when the revised setting is accepted.
3. Press STEP until the display shows P_43. This parameter setting is the “DHW Priority Timeout” parameter. After releasing the STEP button the display will show the current setting. addITIonal dHW fEaTuRES frost Protection With the addition of the IDWH sensor, the Prestige Control module will now provide a Frost Protection feature to the SMART tank. This feature becomes active when Parameter 46 is set to 12 and cannot be overridden.
TRouBlESHooTInG Error codes If Parameter 46 setting is 12 (IDWH Sensor) the following “soft” lockouts could occur: b_38 alternating with a status code of 9 The IDWH Sensor is not properly connected to the Prestige low voltage terminal strip. Check for proper connections and terminations. b_33 alternating with a status code of 9 The IDWH Sensor is short-circuited. Check if the DHW is being used and is properly connected to the Prestige low voltage terminals.
