Danfoss RET2001M Room and Programmable Room Thermostats

Product Information

The RET2001M & TP5001M are electronic controls designed for continuous use in controlling central heating. They have an operating voltage of volt-free and a switch rating of 3A (1) at 250 Vac. The thermostats have an IP30 (installed) rating, load compensation, and on/off control. The product complies with the following EU Directives: Electromagnetic Compatibility 2014/30/EU, Low Voltage 2014/35/EU, Restriction of the use of certain Hazardous Substances 2011/65/EU and amendment (EU) 2015/863. The dimensions of the product are H86 x W86 x D30.

Product Usage Instructions

Before installation, download the user guide from heating.danfoss.com. Installation must be done by an authorized electrician. Follow the below steps for installation:

The room thermostat should be installed at approximately 1.5m above the floor and where the effects of sunlight, draught or other heat sources (e.g. TVs) are avoided.
Loosen the lower retaining screw and carefully remove the backplate.
Mount the backplate directly onto the wall or on a wall box and wire it according to application. Refer to Figs 3 & 5 for wiring diagrams.
Locate hooks at the top of the front part into the top of the backplate and lower into position and tighten the retaining screw.

The product has an accuracy of +/- 1 minute per month with a built-in timer. The product displays error codes E1, EE, Lo, Hi, and E6. Class IV, efficiency gain 2% is the product’s ErP class. Refer to Fig. 4 for dimensions and Fig. 5 for wiring diagrams.

Installation Steps

User Guide can be downloaded from: heating.danfoss.com.

Installation must be done by an authorized electrician.
The room thermostat should be installed at approx. 1.5 m above ﬂoor and where the eﬀects of sunlight, draught, or other heat sources (eg. TVs) are avoided, see ﬁg. 1.
First, loosen the lower retaining screw and carefully remove the back plate, see ﬁg. 2.
Mount the back plate direct to the wall or on the wall box and wire according to application, see ﬁgs 3 & 5 according to application.
Locate hooks at the top of the front part into the top of the back plate and lower into position and tighten the retaining screw.

Dimensions and Wiring

See ﬁg. 4 for dimensions and ﬁg. 5 for the wiring diagram.

Note:

Both live(L) terminals are internally linked and available for ease of cable termination only.
If replacing a 230-volt room stat, a link between the live (L) and a common(COM) terminal is required.
