Part is working great on our Sauna, also! Would use this seller again ! ### ⭐⭐⭐⭐⭐ Works in KIP-80-B *by J***Y on July 24, 2024* Did you forget to remove your thermostat temperature sensor and power on your new 240v circuit to your KIP heater? Welcome to the club!This drop-in replacement prevented me from trashing an otherwise perfectly fine $1000 Harvia KIP-80-B. I have no electrical background and the replacement was not difficult.If you look closely at the back of your thermostat you'll see that the 6 pins are labeled by row and column (31, 32, 21, 11, etc). Do yourself a favor and label all of the wires by their pin number using some sticky notes before you unhook them from the fried thermostat so that you don't need to reference the circuit schematic and trace every single wire back (be sure not to confuse "12" and "21"). Then just swap the new one in and use your notes to connect everything. Done.And don't forget to take out the sensor this time! ### ⭐⭐⭐⭐⭐ Installation was straightforward and it worked on the first go. *by J***K on November 12, 2023* While installing the first thermostat it shorted across a power source and died. This replacement seems to work great. ## Frequently Bought Together - Harvia FH70 Replacement Thermostat for FLB/KIP/JM/KV Sauna Heaters, ZSK-762 Sauna Equipment - amocane Sauna Thermometer 2 in 1 Thermometer Hygrometer for Sauna Room, Sauna Accessories for Any Barrel or Infrared Steam Saunas - HSE Cedar Sauna Aromatherapy Bowl Oil Cup Holder with Swinging Arm and Screw Covers (Red Cedar) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/122779992-fh70-replacement-thermostat-for-flb-kip-jm-kv-sauna-heaters](https://www.desertcart.us/products/122779992-fh70-replacement-thermostat-for-flb-kip-jm-kv-sauna-heaters) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-20*
