Quick Setup instructions for Honeywell 2 & 4 Stage Set point 

These instructions will explain how to set up the Honeywell set point to control heating and cooling with a 4 stage set point.

 1.     Wire the main power and the remote sensor to the Honeywell set point. Refer to the front cover on the set point for proper wiring. (Power and sensor must be wired to program set points)

2.     Turn on the power supply.  When power in applied and the sensor is attached, the system will start a 3 1/2 minute count down.  You can bypass this by pressing any key.  It will then display the current sensor temperature and the stages calling on the lower right corner.

3.     Set the stages for heating and or cooling.

• Press the Select and the Enter buttons at the same time.
• You should see the stage # in the lower right corner and the word sensor on the middle left side. Under the word sensor it will display the mode setting. (heating or cooling)
• Press the up arrow to switch to heating or the down arrow to switch to cooling.
• Press the Enter button to save the change.
• Press the select button to move to the next stage. Then repeat the above process to set the heating or cooling mode for all stages.

4.  Set the Temperature you desire for each stage and the differential.

• Press the select button to display the current set point for stage 1. 
• Press the up or down key to change the set point temperature.
• Press the enter button to save into memory.
• Press the select button to display the differential.
• Press the up or down button till your desired diff. Is displayed.
• Press the enter button to save into memory.
• Repeat process until all stages and differentials are set. When last stage is set press the select button to return to the display screen.

***** Note: After any change you must press the enter button to save the change into the microprocessor of the Honeywell Set points.

For most Hydro-Temp applications where we turn on and off zone valves for well water we will set two set points for heating and two for cooling.  Normal set points would be:

Stage 1 - Heating - 52ºF with 2º Diff.
Stage 2 - Heating - 48ºF with 2º Diff.
Stage 3 - Cooling - 75ºF with 2º Diff.
Stage 4 - Cooling - 82ºF with 2º Diff.
