An AI sales agent's steam humidifier quote, checked before it goes out

An AI sales agent prepares a quote for a CAREL humiSteam X-Plus steam humidifier: the model and supply voltage, the steam distributors and hose, the water supply, probes, a remote display terminal and a supervisory card or SMS modem. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published user manual and returns a verdict, every reason and the figures it computed.

Scope: CAREL humiSteam X-Plus (UEX) isothermal steam humidifiers, UE001 to UE130: model and supply voltage, steam distribution, water supply, probes, remote terminal, supervisor or SMS, and the quote total. See everything this validator covers

This validator models quotes for the humiSteam X-Plus range as described in the public CAREL user manual (+0300040EN, release 1.6, February 2020), not just the scenarios shown below.

  • Model and supply voltage — the fourteen models from UE001 (1.5 kg/h) to UE130 (130 kg/h), the three supply codes (230 V single phase, 230 V three phase, 400 V three phase) the manual lists for each, and the rated steam output, power and current.
  • Steam distribution — the steam outlets of each model, the CAREL linear distributors (DP035D22 to DP205D40) with their inlet diameters and capacities, Y kits, and the steam hose of at most 4 metres.
  • Water and site — supply water hardness (10 to 40 degrees French), conductivity (75 to 1250 microsiemens per centimetre), water temperature, ambient temperature, and the manual's advice against softened water.
  • Control and communication — CAREL room, duct and industrial probes (a main and a limit probe), the remote display terminal at up to 50 metres (EMC filters) or up to 200 metres (TCONN6J000 boards), the serial and BACnet supervisory cards, and the SMS modem kit, which cannot share the single communication line.

Any quote for these products that touches these rules is in scope — not only the scenarios pictured here. Not covered: other CAREL humidifier families (humiSteam basic, humiFog, humiSonic, heaterSteam), cylinder part numbers and ordering codes, master and slave cascades, power cable and fuse sizing, installation hardware, and tax or freight. CAREL does not publish a price list, so the prices in the quote table and the 10 percent discount threshold are illustrative figures modeled from comparable products, not CAREL prices or CAREL policy.

The AI sales agentBuilds the humidifier quote from the conversation and says it is ready.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
A model that is only offered at some supply voltagesOnly with care
Each of the fourteen models is listed for one to three of the three supply codes, so a table of allowed pairs has to be kept in step with the manual.		The model and the voltage are in one request and the pair is checked on every call.
Distributors that do not suit the humidifierOnly with workarounds
The distributor inlet must match the steam outlet, the distributors together must carry the steam output, and a Y kit is needed when there are more distributors than outlets; this is a small calculation, not a field limit.		The capacity, the diameter and the count are computed from the model and the distributor chosen, and compared together.
A remote terminal that needs different parts by distanceOnly with workarounds
Up to 50 metres needs two EMC filters, up to 200 metres needs two TCONN6J000 boards, and beyond that it is not covered; the parts depend on a number the rep types.		The distance decides which parts are required, and a missing part is a blocking finding.
Options that share one communication lineOnly with care
The SMS modem and the supervisory card cannot be used together, so a rule tying two optional lines is needed.		The two options are checked against each other on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases

9The humidifier is installed at an ambient temperature of 41 degrees C; the manual allows 1 to 40 degrees C.
10The steam hose is 5 metres long; the manual calls for CAREL hoses of at most 4 metres and the humidifier needs at least 1 metre to reach the distributor.
11The steam hose is 0 metres long; the manual calls for CAREL hoses of at most 4 metres and the humidifier needs at least 1 metre to reach the distributor.
12The distributor has a 30 mm steam inlet; the humidifier steam outlet and hose are 40 mm.
13The distributors together carry 18 kg/h; the humidifier makes 25 kg/h.
14The distributor has a 40 mm steam inlet; the humidifier steam outlet and hose are 30 mm.
15The distributors together carry 8 kg/h; the humidifier makes 15 kg/h.
16The quote has 3 steam distributors for a humidifier with 1 steam outlet; each outlet needs at least one distributor and, with a Y kit, at most two.
17The distributors together carry 45 kg/h; the humidifier makes 65 kg/h.
18The quote has 1 steam distributor for a humidifier with 2 steam outlets; each outlet needs at least one distributor and, with a Y kit, at most two.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a quote for a CAREL humiSteam X-Plus steam humidifier: the model and supply voltage, the steam distributors and hose, the water supply, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published user manual and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote one CAREL humiSteam X-Plus UE065 on 230 V three phase supply with an openable cylinder, to produce 65 kg/h of steam. Water supply: 25 degrees French hardness, 600 microsiemens per centimetre. The rest of the request is on screen. The quote states a supply current of 70.4 A and a total of $15,645.55.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with four findings, all in one answer. The chosen humiSteam X-Plus model is not listed for the chosen supply voltage in the manual table of models and electrical data. The distributors together carry 45 kg/h; the humidifier makes 65 kg/h. The quote has 1 steam distributor for a humidifier with 2 steam outlets; each outlet needs at least one distributor and, with a Y kit, at most two. The other one is on screen.
    6. 
      
  6. The validator returned four blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for a model that is only offered at some supply voltages, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the supply voltage to 400 V three phase, the steam distributors to 2 x DP125D40R0 and the stated total to $16,011.30.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. The validator also returns the line-item quote. It starts with CAREL humiSteam X-Plus UE065 and Openable cylinder (instead of disposable); the other six lines are on screen.
    13. 
      
  13. All four earlier findings are cleared, and the validator's total, $16,011.30, matches the quote.
    14. 
      
  14. Four problems caught in one call, fixed in one pass, and a clean $16,011.30 quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    15.
