controller recommendation

Zman

I am looking for a couple controllers for wall heaters in a remote building.
They will be controlling a milivolt circuit but can run on 24VAC with common. 12VDC would be preferred.
I would like to put the controller in the mechanical space with only a sensor in the living space.
Nighttime setbacks would be nice for this application. The memory would need to be solid state with no replaceable batteries.
Does anyone have a source for this kind of product?

Controller is kind of a vague term, maybe all you need is a digital thermostat.

Or scroll through the Tekmar catalog or contact them.

A Honeywell 8000 series with a wired remote space sensor would fit the bill I think. Spring for the WiFi flavor (or RedLINK with a gateway) and you'd have remote access as well.

I have some 12 & 24 VDC solar controllers. They have set point functions, sensor can be extended %300 feet. It does keep settings for a year without power. Nice digital display, some logging function, etc
