Paloma MIC-180 - Manual (Page 9)

5. Setting Hot Water Temperature
WARNING: Refer to the safety warnings in this instruction sheet and the water heater
instruction manual before setting the hot water temperature. Temperature can only be set or
changed with the main remote control (UMC-117) wired to the manifold controller.
NOTICE: DIP switch changes to adjust temperature are made on the manifold controller only.
Refer to the water heater instruction manual for setting hot water temperature. The default temperature
range of the main remote control is 100ºF to 120ºF (38ºC to 49ºC). It is possible to change the range
up to 180ºF (82ºC) by making the following adjustments.
Required adjustment for achieving 180ºF (82ºC) maximum water temperature setting (See figure
11 for DIP switch and button locations)
1. Turn off the remote controls. Turn off gas and water
supply to all water heaters in the manifold system.
2. Remove the front cover of the manifold controller
(MIC-180).
3. Find the DIP switch located below the LED display.
4. Change the DIP switch #4 setting on the main
communication PCB to the “ON” position (UP). DO
NOT alter any other DIP switch.
