Extra features
Dual-Energy Models

The TH-400 Dual-energy controller is designed so that one adjustment of the thermostat’s anticipator suits either heating mode.
An electronic fault sensor will automatically transfer from one mode to the other in case of failure of one system. A mode is considered to have failed when it is unable to satisfy the room thermostat for more than 2 hours.
A two-position selector switch allows oil heating or automatic selection according to a timer, an outdoor sensor or a utility off-peak signal.
A green pilot light indicates the mode that has been selected.

Optional Modulation

All models can be equipped with full modulating controls. Add MOD to model number.
