Z wave Binding Examples CT100

This page is an attempt to creating a complete working example of CT100 Thermostat support. I found the parent page only had items so was missing the needed transforms and rules. I also did not want to accidentally break formatting for other entries.

Items

items/CT100.items

Group gHVAC "Heat Pump" (All)

Number HVAC_HeatSetPoint "Heat Set [%.0f F]" <temperature> (gHVAC) {zwave="2:command=thermostat_setpoint,setpoint_type=1,setpoint_scale=1,refresh_interval=20" }
Number HVAC_CoolSetPoint "Cool Set [%.0f F]" <temperature> (gHVAC) {zwave="2:command=thermostat_setpoint,setpoint_type=2,setpoint_scale=1,refresh_interval=20" }

Number HVAC_Battery "Battery State [%d %%]" (gHVAC) {zwave="2:command=BATTERY,refresh_interval=300"}

Note: In My system the CT100 was the first device (after the Z-Stick) so it is NODE 2, in your system you will need to update the NODE to match your configuration. (zwave="2:command...)

Transform files

You will notice that the above items reference 4 different map files. I did find 2 of them mentioned in forum posts but the others I have made up as I go...

transform/thermostatMode.map

-1=Unintialized
0=Off
1=Heat
2=Cool
3=Auto
4=Aux Heat
5=Resume
6=Fan Only
7=Furnace
8=Dry Air
9=Moist Air
10=Auto Changeover
11=Heat Eco
12=Cool Eco
13=Away

transform/thermostatOpState.map

-=Uninitialized
0=Idle
1=Heating
2=Cooling
3=Fan Only
4=Pending Heat
5=Pending Cool
6=Vent / Economizer

transform/thermostatFanMode.map

-=Uninitialized
0=Auto
1=On
2=Two
3=Three
4=Four
5=Five
6=Six

I am fairly sure only 0 and 1 are used, the extra ones are just fillers in case I am wrong. I could not find any documentation verifying this.

transform/thermostatFanState.map

-=Uninitialized
0=Off
1=On
2=Two
3=Three
4=Four
5=Five
6=Six

Again, I am fairly sure only 0 and 1 are used.

Rules

So far I only have a rule that turns on the Fan if the system has been idle for an hour. A simple effort to keep the air an even temperature/humidity in the house. Here in Florida this will typically only happen late at night.

import org.openhab.model.script.actions.Timer

val String PATTERN = "HH:mm "
var Timer timerFanIdle = null
var Timer timerFanCirculate = null
var Integer ruleRunning = 0

rule "Idle Fan"
when
    Item HVAC_Fan_State changed to 0
then
    var String ts = now.toString(PATTERN)
    if (timerFanIdle != null) {
      timerFanIdle.cancel
      timerFanIdle = null
    }
    if (timerFanCirculate != null) {
      timerFanCirculate.cancel
      timerFanCirculate = null
    }
    timerFanIdle = createTimer(now.plusMinutes(60)) [|
        ts = now.toString(PATTERN)
        ruleRunning = 1
  	    sendCommand(HVAC_Fan_Mode, 1)
        sendBroadcastNotification(ts + "Run Fan to circulate")
        timerFanCirculate = createTimer(now.plusMinutes(15)) [|
                ts = now.toString(PATTERN)
          	sendCommand(HVAC_Fan_Mode, 0)
        	ruleRunning = 0 ]
        ]
     }
end

rule "Running Fan"
when
    Item HVAC_Fan_State changed to 1
then
    var String ts = now.toString(PATTERN)
    if (ruleRunning == 0) {
      if (timerFanIdle != null) {
        timerFanIdle.cancel
        timerFanIdle = null
      }
      if (timerFanCirculate != null) {
        timerFanCirculate.cancel
        timerFanCirculate = null
      }
    }

A second set of rules which simply turns on the heat in the morning (to 63F), lowers it to 60F for mid day, and sets it to 59F at night.

rule "climate_morning"                                                 
when                                                                   
  Time cron "0 40 6 1/1 * ? *"                                         
then                                                                   
  logInfo("climate", "Temp: " + HVAC_Temperature.state + "; Target: 63")  
  sendCommand(HVAC_HeatSetPoint, 63)                                   
end                                                                    
                                                                       
rule "climate_day"                                                     
when                                                                   
  Time cron "0 0 11 1/1 * ? *"                                         
then                                                                   
  logInfo("climate", "Temp: " + HVAC_Temperature.state + "; Target: 60")  
  sendCommand(HVAC_HeatSetPoint, 60)                                   
end                                                                    
                                                                       
rule "climate_night"                                                   
when                                                                   
  Time cron "0 30 22 1/1 * ? *"                                        
then                                                                   
  logInfo("climate", "Temp: " + HVAC_Temperature.state + "; Target: 59")  
  sendCommand(HVAC_HeatSetPoint, 59)                                   
end
