Thermostat Bard Part #8403-058
Replacement Instructions
Thermostat Bard part number 8403-058 (Honeywell TH5220D1151) is replacing nine (9) thermostats as part of
Honeywell’s obsolescence of mercury bulb thermostats and older platform digital thermostats. (See Page 2.)
The TH5220D version of thermostat is a multi-purpose design that can be configured for either heat pump
(2 heat/1 cool) or for heat/cool (up to 2 heat/2 cool). The factory default settings out of the box are as follows:
1.
Configured for Heat Pump—Setup Function 1, System Type 5. For Heat/Cool applications it is
recommended to simply change to System Type 6, which is 2 Heat/2 Cool Conventional and use Y1, Y2
if applicable and W1, W2 if applicable.
2.
Changeover (Reversing) Valve— Setup Function 2, Setting 1, which is energized in Heating mode and
which matches all Bard air-to-air heat pumps and QW-Series water-to-air heat pumps. For Bard GSVS-
Series that have reversing valve energized in cooling mode change this must be reset to Setting 0.
