//MHF:10/28/05 Fixed pid bug ,the PID was winding up past 100, taking too long to wind down. 

//             Also in the deadband region, made sure the I term can decay but will not incease. 



//MHF:10/28/05 Added 0---50% item for output table to determin how much the valve open.now the EEP_VALVE_OPER_TABLE_BEGIN register every bit is defined  like this:

//            bit 7 : '0' heating valve(output7)not select 0---50% ;  '1' heating valve(output7)select 0-----50%  

//            bit 6 : '0' cooling valve(output6)not select 0---50% ;  '1' cooling valve(output6)select 0-----50%  

//            bit 5  4  :  floating valve ,the range of valve open

//            bit 3  2  :  heating valve(output7), the range of valve open

//            bit 1  0  :  cooling valve(output6),the range of valve open



//MHF:10/31/05 After a load of the configuration file or new hex file of the same rev number, the occupied state is left unchanged. 

//                                 (if the hex file is a major update requiring the flash to be erased, 

//                                   then the occupied stat is lost after a hex file s sent. )

//             changed file :serial.c 

//			   fixed some code when POM == 1,	in this mode,only when fan_speed_usee ==0 do something

//             changed file :tstat.c 



//MHF:11-07-05 when tstat at unoccupied status ,recaculate cooling_db and heating_db to make PID work correctly

// 			   changed setpoint() and update_pid() function



//MHF:11-09-05 Fixed calibration bug which if  TSS = 0,could not calibrate



//MHF:11-10-05 Fixed LED status,turn all leds off except OFF led when the tstat working in the OFF mode, the left vertical row of status leds.



//MHF:11-11-05 Fixed occupied status in REG184,if the fan speed goes greater than 0 from the keypad, then the occupied bit goes to 1 (TRUE)

//                                             if Fan speed goes to zero from the keypad, the occupied bit is 0 (False). 

//                                             at night, if the fan goes on to maintain the night setpoint, 

//                                             then the occupied bit stays at 0.

// 

	   			

//MHF:11-11-05  limit TSS less than 2 if the tstat is 5A or 5B  ,because the tstat 5A and 5B only have 

//				temperature chip and external thermostor



//REV26.6



//MHF 9/23/05 Add DDC mode in AUTO_ONLY regiser to make the user can not change setpoint and ON/OFF mode from keypad.

//	      	  The user only can change these things from serial port.



//MHF 9/23/05  Add interlock for each output.Add seven registers 285 to 293 to store the interlock, connected to inputs only (for now). 



//MHF 9/27/05  Added a new register to adjust the setpoint increment as a user variable. We store it as a user defined variable 

//			   in a one byte register, minimum value is 0.1, the maximum value could be set at 1.0.Now cooling setpoitn and 

//				heatinng setpoint are stored in the E2 chip by using two bytes.Whatever the setpoint be set by keypad or serial port 

//             the setpoint value should multiply 10.



//MHF 9/28/05  Tss register is left unchanged when the user changes C to F or  F to C.



//MHF 9/28/05  Added a new item DEF which store current configuration  into flash as new default in the menu



//MHF 10/5/05  Tstat displays "---" when the tstat can not detect the pic chip though there is a pic chip

 

//MHF:10/24/05 if the tstat is working on OFF mode,turn off cool and heat LED, lower row of status leds. 





//REV26.5



//MHF 9/6/05 shorten the delay between chatacters when tstat response .the tstat response should have a pause between two characrers,

//           but the maximum allowed pause is 1.5 character times or .83 ms * 1.5 or 1.245 ms at 9600 baud.



//MHF 9/21/05 The baudrate does not change after changed C to F or back.



//MHF 9/22/05 Fixed bug in TSS register.Because the TSS can not be set to zero even that the tstat has internal teperature

//			  sensor when update the tstat's software from before revision 26.4  to after revision 26.4 .



//REV26.4



//MHF 8/18/05  Added "floating valve" feature.Added five  registers from 280 to 284 to determine relay1 to relay5 output mode.

//			   Relay 4 and relay5 be used to control valve by pulse mode if MODE_OUTPUT4 AND MODE_OUTPUT5 be set '1'.

//			   in this mode,the relays not be controled by PWM.



//REV26.3



//MHF  8/18/05 fixed the original PID's Pterm = cooling_db+heating_db+10 to avoid always staying coasting mode

//             because of  the user set the Pterm less than cooling_db plus heating_db



//REV26.2



//MHF 7/12/05 Added PWM to pin ENABLE_2003, for decrease the current by using pulse control relays.
