My backup heater is an empire dv35sg, and it’s controlled by a low voltage reed switch thermostat (millivolt). The model of the thermostat is rk130eaw. I’m wondering if the thermostat can be adjusted for a more narrow on/off cycle. From the factory, it’s set at a little better than a 4 degree cycle. The instructions are a bit confusing since they address moving the anticipator for adjustment on the 24v model, but it’s unclear if this is also relevant for the millivolt model. They also don’t provide any visual guide, and on my thermostat there seems to be two separate adjustments. Thanks, Daniel
