Pentair UltaTemp Heat Pump
The Pentair UltraTemp is a Heat Pump with models having 70,000 to 140,000 BTUs of heating capacity. Some models include a chiller capability.
UltraTemp Power Requirements
All models require 230V AC power and except for the 70,000 BTUs, which requires a 40A circuit breaker, other models require a 50A circuit breaker.
Pentair Heat Pump Calculator
Pentair has a Heat Pump Calculator to determine the appropriate size Heat Pump for your location.
The UltraTemp Heat Pump can be controlled by Pentair automation - IntelliCEnter, IntelliTouch, Easy Touch.
UltraTemp and MasterTemp Heaters Together
You can have both a Pentair MasterTemp gas heater and a UltraTemp Heat Pump on a pool. They are plumbed in line and hooked up to the IntelliCenter via RS-485 cable. In the programming you have a choice of heaters for your spa and/or pool.
The automation is supposed to regulate temperature via the heat pump 1st - if it can not maintain temp it reverts to the gas heater. But after that it does not go back to the heat pump to maintain. You have to switch it manually.
UltraTemp Chiller Mode
When in chiller mode Pentair forgot to link the temperature differential up to the chiller portion. So if you have a chiller set point of 87 degrees, and your temperature bounces back and forth between 88 and 87 degrees - your fan will cycle on/off, on/off, on/off until the temperature is a constant 87 degrees. That will eventually burn the fan motor up.
