Predictika · Large heat pump orders

An AI sales agent's large heat pump order, checked before it goes out

An AI sales agent prepares an order for a large outdoor air/water heat pump from the AxAir Purple HP or Black HT EVO range: the size, the heating and cooling load, the flow temperature, the sound version and the options. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published brochure and returns a verdict, every reason and the listed values it compared against.

Scope: AxAir Purple HP (R290, 19 sizes) and AxAir Black HT EVO (R513A, 12 sizes) outdoor air/water heat pumps: output, flow temperature, sound version and options. See everything this validator covers

This validator models figures and option lists stated in the Meier Tobler Grosswaermepumpen brochure (02-2023), not just the scenarios shown below.

  • Heating output — a heat load above the listed heating output at A-7/W35 for the chosen size, or a stated output at A7/W35 that differs from the brochure, is blocked.
  • Cooling output — when cooling is ordered, a cooling load above the listed output at A35/W7 for the size is blocked.
  • Flow temperature — the maximum flow temperature listed for the family at the design outdoor temperature (Purple HP 62 C down to -10 C; Black HT EVO 80 C down to -5 C and 75 C at -7 C); a design temperature below -20 C is outside the listed operating range, and a temperature with no listed flow figure goes to a person.
  • Sound — the sound pressure level at 10 m for the size and sound version (Black HT EVO standard, LN minus 2 dB(A), SLN minus 4 dB(A); Purple HP figures are for the LN version) against a site limit.
  • Options — the inverter compressor is on the Purple HP option list only, SLN is not listed for Purple HP, and only Modbus and BACnet are listed (not LON); an option the brochure does not list for that family goes to a person for confirmation with Meier Tobler.

Any order for these two heat pump families that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Meier Tobler publishes no public price list for these units, so there is no price build-up or line-item quote), the other large heat pumps in the brochure, the Purple HP sizes 22.1 and 40.2 (their cooling figures in the brochure look inconsistent with neighboring sizes and were left out), cascading limits, hydraulics and electrical sizing.

The AI sales agentBuilds the large heat pump order 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
Output that depends on the exact sizeOnly with care
Each of 31 sizes has its own heating output at A-7/W35 and cooling output at A35/W7, so the table has to be kept in sync with the brochure for every size.		The size sets the listed values once, and the load is compared with them on every call.
Flow temperature that depends on outdoor temperatureOnly with workarounds
The maximum flow temperature changes with the outdoor temperature and differs between families, so a flat limit is wrong and a missing figure has to be told apart from a pass.		The limit is derived from the family and the design outdoor temperature, and a temperature with no listed figure goes to a person.
Sound level that depends on the versionOnly with workarounds
The sound pressure level of Black HT EVO is the standard figure less 2 or 4 dB(A) for LN and SLN, while Purple HP figures are for the LN version only.		The version adjusts the listed sound level, and the result is compared with the site limit in the same pass.
Options listed for one family onlyOnly with care
An inverter compressor or a super low noise version is listed for one family and not the other; a product rule per option has to carry it, and a CPQ either blocks or allows it, with no way to say that Meier Tobler should confirm it.		Each option is a rule against the family, evaluated together with all the others.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order 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.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for a large outdoor air/water heat pump from the AxAir Purple HP or Black HT EVO range: the size, the heating and cooling load, the flow temperature, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published brochure and returns a verdict, every reason and the listed values it compared against.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote an AxAir Purple HP 15.1 large heat pump to cover a heat load of 31 kW at A-7/W35. The order includes EC fans, the hydraulic module, Modbus communication. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The heat load to cover is 31 kW at A-7/W35; the brochure lists a heating output of 28 kW at A-7/W35 for this size. The order states a heating output of 45 kW at A7/W35; the brochure lists 41 kW for this size. The required flow temperature is 65 C; the brochure lists a maximum flow temperature of 62 C at a design outdoor temperature of -7 C.
    6. 
      
  6. The validator returned three 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 flow temperature that depends on outdoor temperature, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the heat pump to AxAir Purple HP 20.1, the flow temperature to 60 C and the stated heating output at A7/W35 to 49 kW.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All three earlier findings are cleared.
    13. 
      
  13. Three problems caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    14.
