Figure 6-5Parameter Set 2E

Parameter 2EB sets the pump delay time for the boiler pump after an over-temperature condition. This time is adjustable from 0 minutes to 40 minutes. The default time is 2 minutes.

If the boiler pump or HW pump have not been active in a 24 hour period, the SMART TOUCH will activate the appropriate pump for a programmed time to prevent jamming. The boiler pump time can be changed by accessing parameter 2EC. This time is adjustable from 0 minutes to 40 minutes. The default time is 20 seconds. The HW pump time can be changed by accessing parameter 2ED. This time is adjustable from 0 minutes to 40 minutes. The default time is 20 seconds.

Set 4: Menu values

Set 4 contains parameters that can be accessed from the boiler display. The parameters in this set control the basic operation of the boiler. To access these parameters, click on Parameters at the top of the Main Screen window (FIG. 6-1, page 10), then click on Set 4: Menu Values on the pull-down menu (FIG. 6-6).

Space Heating (SH) user setpoint (User Setp)

The SH User Setpoint sets the water temperature setpoint for fixed operation or the maximum temperature setpoint when the outdoor air sensor is used. This parameter can be changed by accessing parameter 4AA. The temperature range of this parameter is 50°F to 190°F. The default value is 125°F.

SH min user setpoint (Min User Setp)

The SH Minimum User Setpoint sets the minimum water temperature setpoint that can be used for space heating operation. The user or installer will not be able to program the control with a lower SH setpoint. This parameter can be changed by accessing parameter 4AB. The temperature range of this parameter is 0°F to 190°F. The default value is 70°F.

SH max user setpoint (Max User Setp)

The SH Maximum User Setpoint sets the maximum water temperature setpoint that can be used for space heating. The user or installer will not be able to program the control with a higher SH setpoint. This parameter can be changed by accessing parameter 4AC. The temperature range of this parameter is 0°F to 190°F. The default value is 190°F.

SH turn-off differential (SH off df)

The SH Turn-off Differential sets how many degrees above the Max. Cascade setpoint (parameter 4AY) the outlet temperature has to go before the boiler will shut off. This parameter can be changed by accessing parameter 4AD. The temperature range of this parameter is 0°F to 86°F. The default value is 10°F.
