Triangle Tube outdoor reset settings

t300

I have a Triangle Tube instinct combi 199, in Manitoba. Winter lows -30c, average -15c, and summers get to +25-30c. It was installed without outdoor reset. I bought one, about to hook it up, just wondering on initial settings. I have unit heating at max 150f which seems to work well. Below settings to start seem appropriate?

Parameter	Description	Setting
4	CH Max Setpoint	150°F (Default 186f)
10	CH Min Setpoint	110-120°F (Default 64f)
11	Outdoor Temp at Max Setpoint	-25 to -30°C (-13 to -22°F) (default 0f)
12	Outdoor Temp at Min Setpoint	10-15°C (50-59°F) (default 86f)

It is difficult to provide guidance on the setting simply because we don't know the size of the building, the radiation it has, and the the amount of insulation and air sealing that it has.

Your values are fine IF the building can maintain your desired indoor temperature (not stated). Personally, I would guess that 150°F would not make it at -22°F but the data tells the tale.

If the boiler easily maintains indoor temperature at 150°F supply, experiment with 145°F. You'll get to the point where it will not maintain indoor. Now you are very close to your CH max limit. This must be done at -22°F or so. If warmer, it will skew the results.

Regarding CH min, you'll have to wait until summer to determine. I'd suggest that 100°F would be a good starting point for that. You don't need much heat at 55°F.
