Configuring The Control For High/Low Control - Thomas & Betts ENERGYMIZOR 2 Gebrauchsanleitung

CONFIGURING THE ENERGYMIZOR 2 (HIGH/LOW TYPE)
PROG / CODE ENG / 4) SET UP / 1) CONFIG / HILO <1>
HIGH FLAME BOOST
Enabling this option gives the following functionality.
Whenever there is a heat demand, both high and low relays are activated. After 1 minute the system checks
to see if both high and low relays are required. If the temperature is within the differential programmed, the
high flame relay is switched off.
HIGH/LOW DIFFERENTIAL
When the Energymizor 2 is being used to control a two stage heater, you must enter the hilo differential
setting.
• You are now prompted to enter the HiLo differential.
• A differential setting of 4 and a required temperature of 20°C means that the control will have low and high
flame active until the actual temperature reaches 16°C. At this point, the high flame will be switched off.
DOUBLE IGNITION
Enabling this option gives the following functionality.
When the heat relay is activated for the first time of each switching time, it will switch off after 30 seconds.
Then after a further 10 seconds the relay is re-energised and will operate as normal.
This operates at the start of every switching period and is used to ensure
that the heater fires when installed in areas where there is a high level of
condensation.
PROVING SWITCH
You are now prompted to select whether you have a proving switch
on the system.
When there is a demand for heat, the Energymizor looks to ensure that the proving switch is made. The heat
outputs (High/Low) will be energised when the switch is made.
UP/DOWN TEMPERATURE LIMIT
You are now prompted to enter the limit for the Up/Down temperature
keys. With a limit set to 02, you can increase/decrease the set
temperature by 2°C
