Controls

Clogged filter detector

This device is mounted in the filter section. The sensor measures the difference in pressure before and after the filter section. The information is sent to the THP03 thermostat, to a Tracker™ or to a BMS.

Smoke detector

This device is used to detect smoke in the air stream. It includes a factory mounted detector connected to a central panel, both fitted in the fan section.

When smoke is detected, it shuts off the unit. A dry contact is available on the control panel for a remote default.

High temperature safety thermostat

This additional safety device is a manual reset thermostat for gas fired units (YKD/YKH), required mainly by the French ERP regulation. It is located in the gas burner section. It stops the gas burner and the supply air fan when the supply air temperature rises to 120°C.

Remote fault relay

This is a factory mounted relay used to send alarm signals (dry contact) to a local BMS or a local control panel. With this relay, the compressor, heating, fan and power supply alarm output signals from the controller are reported to a single dry contact.

Thermostats

6 thermostats are available:

THS01/THP01, THS02/THP02 and THS03/THP03.

"THS" are non programmable thermostats, "THP" are programmable.

01 and 02 series are conventional thermostat, 03 series are dedicated to the controller.
