Hi,

I have a model with 233 zones. Right now, every zone has a water loop heat pump. I want to convert these all to packaged single zone systems. To do this, I am working in the .inp file and doing a "find and replace" in NoteTab. The replacing of the system type is easy. I simply search for the "type = HP" line and replace with "type = PSZ". However, the PSZ system requires a control zone. I would like each control zone to be the zone in which that particular system resides. Which means, for each of my 233 zones, I will have a different control zone (i.e. no longer a simple find and replace search).

Does anyone know of a way to use "find and replace" (or another method) to set each control zone with the zone name which the system resides?

This is what the .inp file should look like for a packaged single zone system:

"EL1 Sys1 (PTAC) (G.SSW1)" = SYSTEM
TYPE = PSZ
HEAT-SOURCE = HEAT-PUMP
ZONE-HEAT-SOURCE = NONE
SIZING-RATIO = 1
COOL-SIZING-RATI = 1
MIN-SUPPLY-T = 58
FAN-SCHEDULE = "S1 Sys1 (PTAC) Fan Sch"
CW-LOOP = "DEFAULT-CW"
COOLING-CAPACITY = 15752
COOL-SH-CAP = 11839
HP-SUPP-SOURCE = NONE
FURNACE-HIR = 1.24067
CONTROL-ZONE = "EL1 SSW Perim Zn (G.SSW1)"
C-EER95 = 8.24
C-COP47 = 0.78
C-AFUE = 0.78
C-SF-MTR-TYPE = 1
C-RF-MTR-TYPE = 1
C-OSA-DMPR-CTRL = 1
C-HTG-DUCT-LOCN = *Ceiling Plenum*
C-HTG-DUCT-RVAL = 7
C-CLG-DUCT-LOCN = *Ceiling Plenum*
C-CLG-DUCT-RVAL = 7
C-CLG-CAP-CATEG = 14

For my next system, everything would be exactly the same except the highlighted lines (and so on for all 233 systems):

"EL1 Sys1 (PTAC) (G.W2)" = SYSTEM
TYPE = PSZ
HEAT-SOURCE = HEAT-PUMP
ZONE-HEAT-SOURCE = NONE
SIZING-RATIO = 1
COOL-SIZING-RATI = 1
MIN-SUPPLY-T = 58
FAN-SCHEDULE = "S1 Sys1 (PTAC) Fan Sch"
CW-LOOP = "DEFAULT-CW"
COOLING-CAPACITY = 15752
COOL-SH-CAP = 11839
HP-SUPP-SOURCE = NONE
FURNACE-HIR = 1.24067
CONTROL-ZONE = "EL1 Sys1 (PTAC) (G.W2)"
C-EER95 = 8.24
C-COP47 = 0.78
C-AFUE = 0.78
C-SF-MTR-TYPE = 1
C-RF-MTR-TYPE = 1
C-OSA-DMPR-CTRL = 1
C-HTG-DUCT-LOCN = *Ceiling Plenum*
C-HTG-DUCT-RVAL = 7
C-CLG-DUCT-LOCN = *Ceiling Plenum*
C-CLG-DUCT-RVAL = 7
C-CLG-CAP-CATEG = 14

thank you,
