4. When space temperature is lower than temperature setpoint, dap4 will send a 0-10 VDC signal
to SCR reheat as follow:
When temperature drops, Y4 output signal is:
0VDC when R/A temp = Temp SP- Temp DB
1VDC when R/A temp = Temp SP- Temp DB - 0.1 SCR Pro. band
2VDC when R/A temp = Temp SP- Temp DB - 0.2*SCR Pro. band
3VDC when R/A temp = Temp SP- Temp DB - 0.3*SCR Pro. band
4VDC when R/A temp = Temp SP- Temp DB - 0.4*SCR Pro. band
5VDC when R/A temp = Temp SP- Temp DB - 0.5*SCR Pro. band
6VDC when R/A temp = Temp SP- Temp DB - 0.6*SCR Pro. band
7VDC when R/A temp = Temp SP- Temp DB - 0.7* SCR Pro. band
8VDC when R/A temp = Temp SP- Temp DB - 0.8*SCR Pro. band
9VDC when R/A temp = Temp SP- Temp DB - 0.9*SCR Pro. band
10VDC when R/A temp = Temp SP- Temp DB - SCR Pro. band
When temperature rises, Y4 output signal:
0VDC when R/A temp = Temp SP
1VDC when R/A temp = Temp SP - 0.1 SCR Pro. band

4VDC when R/A temp = Temp SP - 0.4*SCR Pro. band
5VDC when R/A temp = Temp SP - 0.5*SCR Pro. band
6VDC when R/A temp = Temp SP - 0.6*SCR Pro. band
7VDC when R/A temp = Temp SP - 0.7* SCR Pro. band
8VDC when R/A temp = Temp SP - 0.8*SCR Pro. band
9VDC when R/A temp = Temp SP - 0.9*SCR Pro. band
