The control that monitors the cutoff temperature may need to be adjusted. Your hetpump may also work effectively at 16 degrees. you have not left any information on the make or model of the heatpump or the thermostat.
Sorry for your troubles ,
Temperature Hand in dash reading NORMAL ?
Does it Turn Blue to Red if so is do you feel friction or restraint like your turning something rather than freewheeling (smooth fast turning) or Digital and or does it show that it should be warm and not cold ?
Does the TEMP change at all(even the least little bit could narrow the results down) when knob is turned?
POSSIBLE - The Actuator/Motor that switches the VENTS very well could be BAD , Temperature Switch / Climate Control Switch (hot to cold could be broke at the base and only allowing the knob to turn and not in the switch ) Thermostat may be stuck open (keeping the engine running cool and smooth but no heat , maybe just a slight TEMP change when switched from Cold to Hot ). The A/C Switch is pushed in or turned on or broke and is stuck ON
FIXES - 1st- Check FUSES - If Temp HAND Reads Normal it not your THERMOSTAT. - Change the Control Switch / Temp switch - Check A/C Button/Knob . AUTOZONE is my place of business they PRICE MATCH AS WELL!

Check your filter cycles and switch spa into Standard Mode as you have it in Economy. (In Economy mode it will only heat during the filter cycles). If the Ecn or Ec Message is Alternating with the Water Temperature on the Display, the Spa is Operating in the Economy Heating Mode.
If the Ecn or Ec Message is ON Solid (Not Flashing) on the Display, the Spa is Operating in the Economy Heating Mode, but there is No current water temperature because the Spa is between Filter Cycles.
Ecn or Ec is Alternating with Temp: The Spa is Operating in the "Economy" (Ecn or Ec) Heating Mode.
The Water Temperature is Sampled Only during Programmed Filter Cycles. The Heater will Only operate and Heat up to Set Temperature during the Filter Cycles. The Water Temperature will probably drop Below Set Temperature between Filter Cycles. Other Heating Modes are Standard, Standard in Economy, and Sleep Modes.
Ecn or Ec is ON Solid (Not Flashing): The Current Water Temperature is "Unknown" (- - - or - -) while in Economy or Sleep Mode.
Between Filter Cycles, while in the Economy or Sleep Heating Modes, the Pump has not turned ON and the Last Water Temperature is not Current. To read the Current Water Temperature, either Change to Standard Heating Mode or turn On the Heating Related Pump, and wait at least 2 Minutes.
It sounds like the fan limiter switch is going bad. This switch waits until the air temp is high enough for heating the house before allowing the fan/blower to come on. There is another switch that shuts off the blower when the air drops to a certain temp, or it may be the same switch that does both jobs. Hope this helps.
If you have automatic valves that switch over to run the spa, make sure that the valves turn completely to where they are supposed to be. Normally it will be about 180 degrees from where they are when in pool mode. If you have to change the valves over manually, make sure they're in the proper position. The only time this can happen is if the valves are not in the right position allowing the heated water to return to the pool. The thermostat on the heater will heat the water to the prescribed temperature no matter how you have the valves set. So if you place it on spa mode, it will heat whichever body of water that is flowing through it to that temp. If you have an automation system, double check the valves. That is probably where your problem lies.

Try resetting. To reset a Rank A error follow these steps: 1. Turn OFF the Main Power Switch. 2. Turn Main Power Switch ON while pressing the Utility/Counter key. 3. Touch [Trouble Reset]. 4. Check to make sure that [OK] is displayed and the it has been reset. 5. After turning off the Main Power Switch, turn it on again more than 10 seconds after and check if the machine starts correctly.
If the error recurrs then do the following:
1 Check the Fusing Unit for correct installation (whether it is secured in position). 2 Check the Fusing Unit, PWB-M and PU1 for proper connection and correct or change as necessary. 3 Change Fusing Unit 4 Change PWB-M 5 Change PU1
